I'm pretty sure that the volume is 1520.5
Hope this helps you out Superme485!
I can’t see the whole thing take a picture of it again or explain the problem to me
W= l - 5 where w = width and l = length
area = 84 = l*w = l(l-5)
l(l-5) = 84
l^2 - 5l - 84 = 0
(l - 12)(l + 7) = 0
l = 12
length = 12 and width = 7
