The depth of a cuboidal pond with length of 20 m and breadth of 18.5 m is 3.2 m, let us write by calculating the time required to irrigate whole water of the pond with a pump having the capacity to irrigate 160 kilo lit 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 breadth of 40 m, then what is the depth of water in that land – let us write by calculating it. [ 1 cubic metre =1 kilo litre] Open Answer »
The weight of a wooden box made of wooden planks with the thickness 5 cm along with its covering is 115.5kg. But the weight of the box filled with rice is 880.5 kg. The length and breadth of inner side of the box are 12 dcm and 8.5 dcm respectively and the weight of 1 cubic dcm rice is 1.5kg. Let us write the inner height of the box after calculation. Let us calculate the total expenditure ot colour the outside of the box, if the rate is Rs. 1.50 per sq.dcm. Open Answer »
