Answer by Jstrasner(112)   (Show Source):
You can put this solution on YOUR website! Hey,
For this one, you find the area of all the sides, and beacuse there are two you multiply each area by two:
4 x 5 = 20 x 2 = 40
4 x 8 = 32 x 2 = 64
5 x 8 = 40 x 2 = 80
40 + 64 + 80 = 184 feet square
I hope this helps!
