i) and

ii) shopkeeper is honest and and gave good advise.

Step-by-step explanation:

Given : Two types of water tankers are available in a shop. One is in a cubic form of dimensions 1 m x 1 m x 1 m and another is in the form of cylindrical form of diameter 1 m and height is also 1 m. The shopkeeper advises to purchase cuboid tank to a customer.

To find : (i) Calculate the volume of the both tankers.

(ii) Which value is depicted by the shopkeeper?

Solution :

i) Dimension of a cube is 1 m × 1 m × 1 m

Volume of the cube is

Dimension of the cylinder is

diameter d=1 m and radius r=1/2 m, height of the cylinder is h=1 m.

The volume of the cylinder is

ii) The volume of cubical tank is more than that of cylinder.

So, shopkeeper is honest and and gave good advise.
