Question

the Length breadth and height of a cuboid are in the ratio 5: 3:2 if its volume is 240 cm³ find its dimension also find the total surface of the cuboid

Answer 1

lbh=240
5x×3x×2x=240
x^3=8
x=2

so l=5x=10
b=3x=6
h=2x=4
now you can find tsa

Answer 2

Ratio of length to breadth to height= 5:3:2
let the length=5x
breadth=3x and height =2x
A/q,. Volume of cuboid =l*b*h
5x* 3x* 2x =240cm*cm*cm
30x*x*x= 240cm*cm*cm
x*x*x*= (240÷30) cm*cm* cm
x*x*x=8cm
