The dimension of a rectangular box are in the ratio `2:3:4` and the difference between the cost of covering it with sheet of paper at the rate of `Rs .4 and R s .4.50 per s q u a r e m e t e r` is `R s .416.` Find the dimensions of the box.

Explanation

let dimensions are`=2x,3x,4x`

difference between the cost of covering it with sheet of paper at the rate of Rs 4 and Rs.4.50 per
m^2`=Rs 416`

`2(lb+bh+hl)[4.50-4]=416`

`2(6x^2+12x^2+8x^2)xx0.5=416`
`x=4`

so dimension are`=8m,12m,16m`
