Volume of Prisms


Volume is the measure of space occupied by a solid. Another way it is often thought of is how much an object can hold.

To find the volume of a rectangular prism, we simply multiply Base x Height, where the base is the area of the base.

The same is true for triangular prisms, but we have to think of the triangular sides as the base. To find the volume, simply find the area of a triangular base and multiply by the height.

For cylinders, find the area of one of the circular ends, then multiply by the height.

As you can see, they all follow the same pattern – Area of Base x Height.
