A container with square base, vertical sides, and open top is to be made from 2700 square feet of material. Find the dimensions (length × width × heigth) of the container with greatest volume.

    volume=s^2*h s is the base length.

    but 2700=s^2+4sh
    from that, sh=(2700-s^2)/4

    then
    volume= s(2700-s^2)/4
    now, take the derivative of with respect to s...

    dV/ds=0=2700/4 -3s^2/4
    solve for s
