Question

a beam has a total volume of 60 ft cubed. find the max horizontal gap that the beam can span

Answer 1

V = L*W*H
lets say L is horizontal length
L = V/(W*H)
L = 60/(W*H)
inverse relationship, L increases as W and H decrease
without any other restrictions, technically L goes to infinity as W or H goes to 0
so there is no max number, it can span any given length
