the base perimeter is 27.4 yards and the volume is 139.5 cubic yards use the this p=2L+2W or this one p=2(L+W)

2(L+W)=27.4
=>L+W=13.7=>w=13.7-3= 10.7 [9fet=3 yads}
According to the problem 3X10.7Xheight=139.5
Therefore, height =139.5/(3X10.7)=4.35 yards(approax) [

rectangular prism? pyramid? what?
start by plugging the perimeter and length into the p=2L+2W equation and solving for W.
The volume = L*W* Height * fugdefactor, where fudgefactor is 1/3 if it's a pyramid and 1 if it's a prisim. Plug in volume, L, W, and fudgefactor and solve for Height (H).
