Question

A rectangular prism is 3 feet long and 3 feet wide. Its volume is 90 cubic feet. What is the height of the rectangular prism?

Answer 1

We know that:

• Volume of rectangular prism = L × B × H = 90 ft³

Substitute the length, breadth, and height to find the volume of the rectangular prism.

• => 3 × 3 × H = 90 ft³

Now, let's simplify the LHS.

• => 9 × H = 90 ft³

Further simplify the equation by dividing 9 both sides.

• => 9 × H/9 = 90 ft/9
• => H = 10 ft

Thus, the height of the rectangular prism is 10 feet.
