Answer:
5ft
Step-by-step explanation:
In this question, we are asked to calculate the width of a rectangular-shaped prism water storage.
Mathematically, the formula for the volume of a rectangular prism is simply the base area of the rectangular prism by the height of the prism.
Since the area of the base is L * W, the area of the prism shape as a whole is calculated as: L * W * H
Thus, we have: 7 * 8 * W = 280
W = 280/56
W = 5ft
