Question

A cuboidal tank has a length of 30 cm, a breadth of 20 cm and a height of 15 cm. The tank is placed on a horizontal table and it is three-quarter full of water. Find the area of tank which is in the contact with water.

Answer 1

volume of cuboid = l*b*h
=15*30*20
=9000cm3
volume of water =3/4*volume of cuboid
=3/4*9000
=6750cm3
