Answer any two questions : If 64 buckets of water is withdrawn from a cubical water tank, full of water, then 1/3 of water in the tank still remains. If the length of the side of the water tank is 1.2 metre than what is the capacity (in litre) of each bucket? (1 cubic decimeter = 1 litre)

If 64 water - filled buckets of equal volume are taken out from a cubical water - filled tank, then 1/3 th of water remains in the tank. If the length of one edge of the tank is 1*6 metres, then calculate the quantity of water that can be hold in each bucket ?

If 64 water filled buckets of equal measure are taken out from a cubical water fiUed tank, then 1/3 rd of water remains in the tank. If the length of one edge of the tank is 1 ·2 m, then calculate the quantity of water that can be hold in each bucket ?

The base of a water tank is a square of side 3 ft. find the rate of flow of water in the tank, if the water-level at the rate of 1 fr/min.

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.

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.

A cubical vessel of height 1 m is full of water . What is the amount of work done in pumping water out of the vessel ? (Take g = 10 m S^(-2) )

A wooden cubic block with a 200 g mass floats in water just fully immersed. When the mass is removed, the block floats up by 2 cm. The length of each side of the cube is

The depth of a cuboid pond with length of 20 m and breadth of 18.5 m is 3.2 m, determine the time required to irrigate whole water of the pond with a pump having the capacity to irriagate 160 kilolitres water per hour. If that quantity of water is poured on a paddy field with a ridge having the length of 59.2 m and breath of 40 m, then what is the depht of water in that land ? [Let 1 cubic metre=1 kilolitre]
