A cuboidal tank is filled with diesel. That amount of diesel is poured into 240 tins in such a way that each of the tins volume is 15 lit. If the breadth of the tank is 1.5 m and the height of the tank is `3/5th` times of its length, then find the height and length of the tank.

A tank can contain 384 litres of water. The length of the tank is 3 times of its depth and the breadth is 2 times of its depth. Find the depth of the tank.

An overhead water tanker is in the shape of a cylinder has capacity of 61.6 cu.mts. The diameter of the tank is 5.6 m. Find the height of the tank.

The curved surface area of a right circular cone is sqrt(5) times of its base area . Find the ratio of the height and the length of radius of the cone.

The length of a cuboidal tank is 20 metres. The height of the water- level in the tank decreases by 15 cm when 18 kilolitres water is taken out from the tank. Then find the breadth of the tank.

The ratio of length breadth and height of a cuboid is 3:2:1 and its volume is 384 cc, then find the total surface area of a cuboid.

A group of fire brigade personnel carried a right circular cylindrical tank filled with water and pumped out water at a speed of 420 metres per minute to put the fire in 40 minutes by three pipes of 2 cm diameter each. If the diameter of the tank is 2* 8 metres and its length is 6 metre, then calculate (a) what volume of water has been spent in putting out the fire and (b) hte volume of water that still remains in the tank .
