Question

If the length and breadth in ratio 5 : 3 its height is 5cm and volune is 4800 find length and breath

Answer 1

Answer:

Given:

l : b = 5 : 3

So,let there a constant number x,such that l=5 and b=3.

height is given 5cm

We know that the volume of cubid is equal to the product of the dimensions

i.e.  l*b*h=4800

Substituiting the values of length and breadth

5x*3x*5 = 4800

So,x² = 4800/75

x² = 64

So,x = 8.

Thus length =5x=5*8

                    =40cm

& Breadth =3x=3*8

                    =24cm

hope this helps you
