    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
