Question

If the ratio of length breadth and height of a cuboid is 5 ratio 3 ratio 1 and its volume is 120 Cube find its dimensions

Answer 1

Let length,breadth and height be 5x,3x and X

Volume =120cm cube

We know that volume =l*b*h

120=5x*3x*x

120=15x^3

120/15=x^3

8=x^3

X=2

Height =2 unit

Breadth=3*2=6unit

Length=5*2=10unit

Answer 2

Step-by-step explanation:

Let the length: breadth: height=5:3:1

l=5x,b=3,h=1x

120=5x*3x*1x(* means multiply)

120/15=x³

8=x³

x=2

Therefore,

Length=5×2=10m

Breadth=3×2=6m

Height=2m
