Question

find capacity of water tank in litres whose dimensional are 4.2 M, 3M and 1.8 m

Answer 1

capacity=volume×1000
=lbh×1000
=4.2×3×1.8×1000
=22.68×1000
=22680ltrs

Answer 2

Given,
Length= 4.2 m
Breadth= 3 m
Height= 1.8 m
And,
As we know that the water tanks are usually cuboidical
So,
Volume= l*b*h
= 4.2*3*1.8
= 22.68 m³
Now,
1 m³= 1000 litres
22.68 m³= 22.68*1000
= 22680 litres

Hope this helps you!
