If the length, breadth, and height of one packet of one gross match box are 2.8dcm. and 0.9dcm respectively, then let us calculate the volume of one match box. [one gross=12dozen]. But if the length and breadth of one matchbox be 5 cm and 3.5 cm , then let us calculate the height of it.

The height of Chandmari road is to be raised. So, 30 cuboidal holes with equal depth and of equal measure are dug out on both sides of the road and with this soil, the road is elevated. If the length and breadth of each hole are 14 m and 8 m. respectively and if the total quantity of soil required to make the road be 2520 cu m.let us calculate the depth of each hole.

If 64 water filled buckets of equal measure are taken out from a cubical water-filled the 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 let us calculate and write the quantity of water that can be held in each budget?

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

The length and breadth of a rectangular field of the village are 20m and 15 m respectively.For the construction of pillars in the 4 corners of that field 4 cubic holes having the depth of 4 m are dug out and the soils removed are dispersed on the remaining land. Let us calculate and write the height of the surface of the field that is increased by.
