# Given a cylindrical tank, in which situation will you find surface area and in which situation volume.

(a) To find how much it can hold.

(b) Number of cement bags required to plaster it.

(c) To find the number of smaller tanks that can be filled with water from it.

**Solution:**

a) We have to find out the volume of the object to know the capacity of the tank.

b) We find the surface area of the region covered by a boundary, wall or floor to know how many cement bags will be required.

c) Volume of the cylindrical tank should be found to know the number of smaller tanks that can be filled with water from it.
