Question 912708
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
