Answer:
84 square feet
Step-by-step explanation:
The formula for this is V=1/4h square root of (﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4)
but that’s really Complicated
so here’s a simpler way
if we treat this like a rectangular prism, and just multiply the length x width x height it’s way easier. If we split the prism in half and rearrange the pieces, it will just be a rectangular prism.
just multiply the three measures given and divide by two
4 x 6 x 7 = 168
168/2 = 84
the answer is 84 square feet
