Find the surface area of the rectangular prism below.
11 ft must be one side of the prism there are four sides added = 11 + 11 + 5 + 5 = 32 ft
total side area = 15 x 32 = 480 ft2
The little side flaps are then 5 x 11 * 2 = 110 ft 2
total area = 480 + 110 = 590 ft2
I think there is not enough information.
