(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 and Explanation
We calculate the area when there is a boundary enclosing a space, for example, the outer and inner surface area of objects like cylinders, cones, spheres, walls, or floors.
To determine the space taken up by substances such as water, milk, coffee, tea, etc., we need to calculate the volume of the object.
(a) In this situation, we will find the volume.
(b) In this situation, we will find the surface area.
(c) In this situation, we will find the volume.
