Question

the length breath and height of a rectangular soild are in the ratio 6 :5:4 . if the total surface area is 5328cm^2 , find the length , breadth and height of the solid

Answer 1

length = 6x
breadth=5x
height=4x
total surface area = 2*[(6x*5x)+(5x*4x)+(6x*4x)]
=2* (30x^2+20x^2+24x^2)
=2*(74x^2)
= 148x^2=5328cm^2
x^2= 5328/148
=36
x^2=36
x=6
length=6*6=36cm
breadth=5*6=30cm
height= 4*6=24cm
