Best answer as selected by question asker.
Surface Area of a right Rectangular Prism(S) = 2lw + 2lh + 2wh where l is the length, w is the width and h is the height of the rectangular prism.
Here, l = 6 ft, w = 4 ft and S = 108 ft^2. We have to find h.
So, according to the problem:
108 = 2lw + 2lh + 2wh
=2(lw + lh + wh)
or, 108 = 2(6*4 + 6*h + 4*h)
or, 108 = 2(24 + 6h + 4h)
or, 108 = 2(24 + 10h)
or, 108 = 48 + 20h
or, 20h = 108 - 48
or, 20h = 60
or, h = 3
Therefore, the height of the right rectangular prism is 3 ft.
