You can put this solution on YOUR website! a box has a top area of 5400sq cms and a front area of 7200sq cms and an end area of 4800sq cms what are the dimensions of the box in cms?
l * W = 5400
l * h = 7200
w * h = 4800
l * W = 5400/ l * h = 7200
w/h = 3/4
w* h = 4800
Multiply both
w^2= 3600
w= 60 .............
w*h = 4800
h= 4800/60
h=80..................
L*W = 5400
L* 60 = 5400
L= 90
L= 90, W = 60, h=80
