Consider the two shapes separately that makes up the tent:
- volume of rectangle -- L*W*H
- volume of triangular prism -- (1/2)BHL
reference:

.
volume of rectangle:
L*W*H = 15*15*9 = 2025 cubic feet
.
volume of triangle:
(1/2)BHL = (1/2)15*8*15 = 900 cubic feet
.
Total volume = 2025+900 = 2925 cubic feet
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
volume of the tent is the volume of the rectangular solid plus the volume of the rectangular pyramid on top of it.
-----
volume of rectangular solid is length * width * height = 15 * 15 * 9
volume of rectangular pyramid is 1/3 * length * width * height = 1/3 * 15 * 15 * 8
-----
your answer should be:
2025 + 600 = 2625 cubic feet.
-----
there is no pie involved.
