Question

A drum has a square base. When it contains 72litres of liquid, height of the liquid
is 20cm. Find the length of base of the drum.​

Answer 1

Answer:

l=1.89

Step-by-step explanation:

capacity of the drum= 72 litres

capacity of drum = l*b*h

since l=b, (given)

let l be x

therefore becomes x

capacity of the drum= x*x*h

72 = x^2*20

3.6 = x^2

1.89 = x

therefore l = 1.89
