☆Question☆

A cube and a cuboid have same volume. The dimensions of the cuboid are in the ratio of 1:2:4. If the difference between the cost of polishing the cuboid and the cube at the rate of ruppee 5 per sq m is ruppee80, find their volume

☆Explanation☆

As we know , there is given that a cub and a cuboid both have a same volume , and also it is given that dimensions of the cuboid are in ratio = 1:2:4.

Now ,

If the difference between the cost of polishing the cuboid and the ratio of ruppee is

5/²m( 5/square metere) is 80 ruppes then it is asked that we need to find their volume.

As we already know , that the volume which we will find will have same volume of cube and cuboid both.
