Answer:

Option B

80 in²

Step-by-step explanation:

Volume, V of any shape is the product of cross-sectional area and height. Therefore, V=Ah

Where A is the cross sectional area and h is the height.

Making A the subject of the formula then

A=V/h or V÷h

Substituting 400 in³ for V and 5 in for h then

A=400 in³÷5 in=80 in²

Therefore, the area of base is 80 in²
