Volume of Rectangular Prism
The volume of a rectangular prism is the number of cubic units the prism can hold.
This rectangular prism is 3 units long, 4 units wide and 2 units high.
First determine the area of the base.
The area of the base is 3 x 4 = 12 cubic units.
Second, multiply the area of the base by the height to find the volume.
Volume = 12 x 2 = 24
The volume is 24 units3.
When finding volume you are finding the cubic units so you write the result as 24 cubic units or 24 units3 since 3 dimensions are involved - width, height and length.
The formula for finding the volume of a rectangular prism is:
Volume = Area of base x height
This is the same as multiplying width x length x height.
