    the answer is six. I work at home depot. come at me bros

    16 x 12 = 192
    4 x 8 = 32

    192 / 32 = 6

    Done.
    I rep back. 1k+

    lol thats not the true optimization of materials though.

    you would set the constraint as 192ft^2= lw

    isolate one of the variables then plug it back into the equation and get the first derivative for the true answer OP.

    16 x 12 = 192 sq ft
    1 plywood= 32 sq ft
    192 /32 = 6
