Half of the cuboidal water tank with length 2.1m and breadth of 1.5m is filled with water. If 630 lit water is poured more into the tank, then calculate and write the depth that will be increased by.

Half of a cuboidal water tank with length of 2· 1 m and breadth of 1·5 m is filled with water. If 630 litres water is poured more into the tank, then calculate the depth of water that will be increased by.

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 ?

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 ?

The daily requirements of water of three families in our three-storyed flat are 1200 litres, 1050 litres and 950 litres respectively. After fulfilling these requirements in order to put up a tank again and to deposit to store 25 % of the required water, only a land having the length of 2·5 m and breadth of 1 ·6 m has been procured. Calculate the depth of the tank in metre that should be made. If the breadth of the land would be more by 4 dcm, then calculate the depth of the tank to be made.

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]

A tank of length 21 dcm, breadth 11 dcm and 6 dcm deep is half filled with water. If 100 solid iron balls of diameter 21 cm are completely immersed in the tank, then how much dcm of water level is raised?

A boat of length 3m and breadth 2m is floating on water in a lake. When a man rides on the boat, it sinks 1 cm more. The mass of the man is

There were 800 litres, 725 litres and 575 litres kerosine oil in three kerosine oil drums in a house. The oil of these three drums is poured into a cuboidal pot and for this, the depth of oil in drums becomes 7 dcm. If the ratio of the length and breadth of the cuboidal pot is 4 : 3, then calculate the length and breadth of the pot. If the depth of the cuboidal pot· would be 5 dcm, calculate whether 1620 litre oil can be kept or not in that pot.

An outlet pipe in the roof with length 13m and breadth 11m was closed at the time of rain fall. After rain fall, it was seen that water habing logged in the roof with 7cm depth. The length of diameter of outlet pipt is 7cm and water comes our cylindrically with 200m length/min. Calculate the time required is drainout whole amount of water after opening the pipe.
