FAQs on NCERT Solutions for Class 8 Maths Chapter 9 Mensuration
1. What are some of the applications of mensuration in our everyday lives?
In real life, mensuration is applied in many fields like:
Measuring floor and site areas required for purchasing or selling land.
Measuring agricultural fields.
Measuring surface areas of a house required for estimating painting cost.
To know the volume of the level of water in rivers and tanks.
To find out the amount of carpet required for covering a specific room.
The volume of soil that is needed to fill a ditch.
2. What are solid shapes and what is the method of measuring the surface area of a solid shape?
Any 3-D shapes occupying some space are called solid shapes like cube, sphere, cylinder, etc. To measure the surface area of a solid shape, we need to draw the net of that solid shape. From the net, we can see all the faces of the solid clearly. Then, we calculate the areas of each of the faces and add them up to get the total surface area of the solid shape. Surface area is measured in a square unit.

4. The base area of the cuboid is 25cm sq. Its volume is 275 cubic cm. What will be the height of the cuboid?
In the question, we are given the base area of the cuboid which is equal to 25cm sq.
The volume of the cuboid is 275 cubic cm.
We know that according to the formula,
The volume of a cuboid = Height × Base Area
Therefore, the height of the cuboid will be = Volume of cuboid/ Base Area
Height = 275/25 = 11cm
Thus, 11cm is the height of the cuboid.
5. The distance between two parallel sides is 15m and the length of one parallel side is 20m. 480m sq. Is the area of the trapezium-shaped field. What is the length of the other parallel side?
Let one parallel side be a = 20m and the other parallel side is ‘b’.
The height of the field is 15m.
Given, the area of the trapezium is 480m sq.
The formula of trapezium is,
Area of trapezium = ½ (a + b) * h
480 = ½ (20 + b) * 15
20 + b = 480 × 2/ 15
64 = 20 + b
b = 44m
Thus, the length of the other parallel side is 44m.
