The length, breadth, and weight of a brass plate with the squared base are x cm, 1 mm and 4725 gm respectively, if the weight of 1 cubic dcm brass is 8.4 gm, then let us write by calculating the value of x.

If the ratio of length breadth and height of a cuboidal box is 3:2:1 and its volume is 384cc. then let us calculate the total surface area of the box.

The inner length, breadth, and height of a box of tea are 7.5 dcm.and 5.4dcm. respectively, if the weight of the box filled with tea is 52 kg 350 gm., but in the empty state, its weight is 3.5 kg , then let us write by calculating, the weight of 1 cubic cm. tea.

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?
