    so if take for instance I had 5', 4' & 3' as my sides i would take 5x4x3 * 2 for a 120?

    How did you get 120?

  • Math - ,

    5*4*3=60 than 60*2=120 is that right

  • Math - ,

    If a is 5, b is 4, and c is 3, use the equation 2ac + 2bc + 2ab and substitute the variables.
    So...
    (2*5*3)+(2*4*3)+(2*5*4)
    that equals 30+24+40=94
