The volume of a box is 400 in.^3in. 3 . The height is 5 in. What is the area of the base of the box? A 80 in. B 80 in.^2in. 2 C 8 in. D 8 in.^2in. 2

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

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
