Given:
A rectangular prism has a top face with an area of 20 ft² and a height of 5 ft.
We need to determine the volume of the rectangular prism.
Volume of the rectangular prism:
Let us determine the volume of the rectangular prism.
The volume of the rectangular prism can be determined using the formula,
[tex]V=length \times width \times height[/tex]
where length × width = Area of the base of the rectangle.
Thus, the formula becomes,
[tex]V= Area \ of \ base \times height[/tex]
Substituting Area = 20 ft² and height = 5 ft, we get;
[tex]V=20 \times 5[/tex]
[tex]V=100 \ ft^3[/tex]
Thus, the volume of the rectangular prism is 100³
