The material that we will discuss this time is about rectangular pyramid nets. If you've previously studied flat and spaced shapes, of course you'll still remember the quadrilateral pyramid.

One example of a pyramid shape that is very popular and certainly familiar is the very historic Egyptian pyramids. Yes, the pyramid is in the form of a rectangular pyramid which is marked by the shape of the base in the form of a rectangle.

What is Limas?

Previously, the very popular rectangular pyramid shape was exemplified, namely the Egyptian pyramids. In addition, there are many pyramid shapes that we encounter in everyday life, such as telephone towers, tents, and so on.

Limas itself can be interpreted as a three-dimensional spatial shape whose base is a polygon or has many facets, it can be a triangle, a quadrilateral and even a pentagon. While on the sides it is triangular and has a corner or peak at the top.

The name of the shape of the pyramid is adjusted to the shape of the base. If the base is a triangle then it is called a triangular pyramid. Meanwhile, if the base is rectangular, it is called a rectangular pyramid. So, so far, have you understood more about the meaning of limas?

Characteristics of a Quadrangle Pyramid

Characteristics of a Quadrangle Pyramid

A rectangular pyramid or in English called a Rectangular Pyramid is a geometric shape whose base is n-shaped, with the upright side triangular and conical to one point.

In this rectangular pyramid, specifically it has a rectangular base shape. Such as the shape of a square, rhombus, rectangle, parallelogram, kite or trapezoid. Meanwhile, if you dissect a rectangular pyramid, you will find the following characteristics:

  • It has 5 sides in the shape of the space, namely 1 side of the base and 4 conical upright sides.
  • The side of the base of a rectangular pyramid is rectangular.
  • On the four sides upright in the form of an isosceles triangle.
  • Construct a rectangular pyramid with 5 vertices.
  • A rectangular pyramid has 8 edges, consisting of 4 base and 4 upright.
  • The vertical ribs on a rectangular pyramid have the same length.

Based on the characteristics of the rectangular pyramid that has been described above, of course, you have a better understanding of how the image of the space wakes up. Meanwhile, to make a rectangular pyramid, you need to know the nets of the pyramid. The following is an image of a regular rectangular pyramid net:

How to Make a Square Pyramid

How to Make a Square Pyramid

Limas is a form of space that has a net, which consists of an arrangement of sides in the form of a flat plane which, when combined, will form a wake. The way to make a rectangular pyramid is with the following steps:

  • First, please draw a square and 4 isosceles triangles.
  • You can use a ruler so that the size is the same and precise according to the image of the rectangular pyramid net that has been shown previously.
  • If all the nets have been completed and will be combined to form a space, then all you have to do is cut and put all the sides together to form a rectangular pyramid.

Parts of a Quadrangle Pyramid

Parts of a Quadrangle Pyramid

If viewed based on the previous image of the rectangular pyramid net, then in the wake of the rectangular pyramid there are several important parts in it. These sections include:

1. Side or Field

The sides or planes of a rectangular pyramid E. ABCD consist of side ABCD which is the base side, ABE which is the inner side. front, DCE which is the back side, BCE which is the left side and ADE which is the side right.

2. Lateral

In addition, from the image of the rectangular pyramid E.ABCD, it can also be seen that the shape has 8 edges consisting of 4 base and 4 upright edges. The base edges are AB, BC, CD. and DA. And the upright ribs are AE, BE, CE and DE.

3. Corner Point

The number of vertices in the pyramid shape depends on the shape of the base so that each pyramid will have a vertex at the top. The number of vertices on a rectangular pyramid is 5 pieces.

4. Plane Diagonals and Side Diagonals

Basically, the plane diagonals and the side diagonals of a pyramid correspond to the type of pyramid. Thus, the diagonal of the plane and the diagonal of the side of a quadrilateral pyramid have two that are on the side of the base. That is by drawing a line from points A – C and points B – D.

5. Diagonal plane

There are two diagonal planes on a rectangular pyramid that are triangular in shape, namely in the form of a plane formed from the diagonal on the side of the base and two edges. The diagonal plane in question is from the points AEC and BEB.

6. The Height of the Quadrangle Pyramid

What is meant by the height of a rectangular pyramid is the distance drawn from the meeting point of the diagonals on the side of the base with the point at the top of the pyramid. The distance is obtained from the intersection of the diagonals on the sides AC and BD with the vertex being at E.

Quadrilateral Pyramid Formula

If previously discussed about rectangular pyramid nets and their parts, then you You also need to know the formula for the volume of a rectangular pyramid in order to be able to calculate the volume of a rectangle the. Here is the volume formula you need to know.

V = 1/3 x L (base) x t

V: Volume of a rectangular pyramid

L: Area of ​​the base of the rectangular pyramid

t: the height of the rectangular pyramid

Example of a Quadrangle Pyramid

To better understand the application of the formula for the volume of a rectangular pyramid above, here we present an example of a simple problem that can be studied.

1. It is known that a rectangular pyramid E. ABCD has a square base with a side length of 8 cm and a height of 6 cm. Find the volume of the rectangular pyramid E.ABCD.

Problem 1 Square pyramid

Discussion:

V = 1/3 x L (base) x t

= 1/3 x (8 x 8) x 6

= 1/3 x 64 x 6

= 1/3 x 384

= 128 cm'

So the volume of the rectangular pyramid E.ABCD is 128 cm3.

2. It is known that a rectangular pyramid O. ABCD has a square base whose side length is 10 cm. If the height of the pyramid is 9 cm, what is the volume of the rectangular pyramid O.ABCD?

rectangular pyramid O. ABCD

Discussion:

V = 1/3 x L (base) x t

= 1/3 x (10 x 10) x 9

= 1/3 x 100 x 9

= 1/3 x 900

= 300

So the volume of the rectangular pyramid T. ABCD is 300 cm3.

The rectangular pyramid net consists of the arrangement of the sides in the shape of the space. So that when combined will form the desired rectangular pyramid. You can create a rectangular pyramid and calculate its volume according to the formula described previously.
