Calculating Volume

The formula to find the volume multiplies the length by the width by the height. The good news for a cube is that the measure of each of these dimensions is exactly the same. Therefore, you can multiply the length of any side three times. This results in the formula: Volume = side * side * side.

Then, How is the volume of the cube related to the volume of the pyramid?

The volume of a pyramid is 1/3 × (the area o the base) × (the height). If the pyramid has a square base with side length x and the height of the pryamid is x/2 then you can put 6 of these pyramids together to form a cube as in the diagram below.

Considering this, How do we find the volume of a prism?

## What is a 3 dimensional hexagon called?

A 3D hexagon is called a hexagonal prism.

It has two hexagons for bases and six rectangular sides. A hexagonal prism is classified as an octahedron, which is a threedimensional geometric object with eight faces.

## Why is the volume of a pyramid?

Recall that the volume of a prism is its base area times its height. If you compare this to the formula of the pyramid, you will see one is exactly a third of the other. This means that the volume of a pyramid is exactly one third the volume of the prism with the same base and height.

## How many vertices does a sphere have?

(One radius from each sphere connected to one radius from the nuclear sphere.) Each axis is separated by 60 degrees from an adjacent axis. This angle of 60 degrees is a property of the adjacency of the spheres. So a sphere has 12 vertices.

## How do you find the volume of a triangle?

Calculating volume
1. Remember the formula for calculating volume is: Volume = Area by height. V = A X h.
