Answer:
A = 532 ft^2 total
Step-by-step explanation:
There are 3 sets of 2 identical areas: 2 top/bottom, 2 sides, 2 ends.
Suppose the length is 14 ft, the width 7 ft and the height 8 ft.
A = 2 * (base area) + 2 * (end area) + 2 (side area)
= 2 * (98 ft^2) + 2 * (56 ft^2) + 2 (112 ft^2)
= 196 ft^2 + 112 ft^2 + 224 ft^2
A = 532 ft^2 total
