Examples of Class 8 Mensuration Questions

Here are some common examples of mensuration exercises:

Q. Find the circle's diameter, whose circumference is 230 meters.

Solution:

The circumference is 230 meters.

2r = 230m, r = 230, 72, 22, and 36.6m, respectively; 

d = 2r = 2m*36.6m= 73.18cm.

 

Q. A floor tile is shaped like a parallelogram, with a base of 24 cm and a height of 10 cm. How many of these tiles are needed to cover a 1080 m2 floor? (If necessary, you can divide the tiles however you'd like to fill in the corners.)

Solution:

Given: The tile's base measures 24 cm or 0.24 m

The height of a flooring tile is 10 cm or 0.10 meters.

Now, floor tile area equals base plus altitude.

= 0.24×0.10

= 0.024

The tile's surface area is 0.024 m2.

The formula for how many tiles are needed to cover the floor is: Area of floor/Area of one tile (1080/0.024).

= 45000 tiles

Thus, 45000 tiles are needed to cover the floor completely.

 

Q. Daisy is painting the walls and ceiling of a cuboidal hall with length, breadth, and height of 15 m, 10 m, and 7 m, respectively. From each can of paint, 100 m2 of the area is painted. How many cans of paint are needed need to paint the room?

Solution:

The wall measures 15 meters long, 10 meters wide, and 7 meters high

Total Surface Area of the classroom = l x b + 2(bh + hl)

= 15 × 10 + 2(10×7 + 7×15)

= 150 + 2(70 + 105)

= 150 + 350

= 500

Consequently, the required number of cans = hall area / can size

= 500/100 = 5

Therefore, painting the room requires five cans.

 

Q. A hollow cylinder has a lateral surface area of 4224 cm2. It is divided along its height to create a 33 cm wide rectangular sheet. Find the rectangle sheet's perimeter.

Solution:

The hollow cylinder's lateral surface area is 4224 cm2.

33 cm is the width of the rectangular sheet, and let l be its length.

Cylinder's lateral surface area equals the size of a rectangular sheet

4224 = b × l

4224 = 33 × l

l = 4224/33 = 128 cm

The rectangular sheet is therefore 128 cm long.

Also, the rectangular sheet's perimeter is equal to 2(l + b).

= 2(128+33)

= 322 cm

The rectangular sheet has a 322 cm perimeter.

 

Q. Metal Sheet is used to create a closed cylindrical tank with a 7m radius and a 3m height. How much metal sheet is needed?

Solution:

Cylindrical tank's radius, r = 7 m

The cylindrical tank's height is 3 meters.

The total tank surface area is equal to 2r(h+r).

= 2×(22/7)×7(3+7)

= 44×10 = 440

A metal sheet of 440 m2 is needed.

FAQs on CBSE Class 8 Maths Worksheet Chapter 11 Mensuration - PDF

1. What are the Class 8 Mensuration important concepts?

The essential coneptsin Class 8 Mensuration include:

The perimeter is measured in km, m, or cm. Area: The area of any solid geometric shape is the boundary closed surface. The measurement of the area is in km2, m2, or cm2. Surface Area: Any three-dimensional figure's total surface area is referred to as its surface area.

2. Who is the mensuration's founder?

The pioneer of mensuration is Archimedes.

3. What measurements can we do under mensuration?

Mensuration includes two types: 2D mensuration and 3D mensuration.

  • Only two dimensions—length and width—make up the 2D figures. The two-dimensional figure is flat; it has neither height nor depth.

  • Length, breadth, and height or depth are the three dimensions of a three-dimensional figure.

4. What are the perimeter formulas?

P = (L + W) x 2 is the perimeter formula for a rectangle, where P stands for perimeter, L for length, and W for width. You may quickly solve for the perimeter of a rectangular shape when its dimensions are known by simply entering the values of L and W into the formula.

5. What is Mensuration 3D?

Mensuration 3D contains the volume and surface area of the 3-D (dimension) figures. Examples are Cube, Cuboid, Cylinder, Cone, Sphere, Frustum, Pyramid, Prism, Tetrahedron, etc.
