Finding the volume of a shape is a lot similar to finding the area because each shape has its own formula. According to dictionary.com volume is the amount of space, measured in cubic units, that an object or substance can take up.
Lets start by explaining how to find the volume of a square:
The formula is 4/3 x pie x radius squared.
Example:
If you have a circle with a radius of 2 your equation would be:
4/3 x pie x 2 squared
4/3 x pie x 4 = 16.8 cubic units
Then there is finding the volume for objects like a pyramid, rectangle, cylinder, and a cone. The formula for the volume of a pyramid is very simple. the formula is 1/3 x base x height. It is very similar to the area formula for a triangle. The formula for the volume of a cylinder is pie x radius squared x height. And then there is rectangle which is just length x width x height.
Lets try an example for a cone. The formula is very similar to the volume of a cylinder.
1/3 x pie x radius squared x height
So if we have a cone with a radius of 4 and a height of 8 the formula would look like this:
1/3 x pie x16 x 8
and it would equal 134.04 cubic units.
