Question 1
1 / -0

Which of the following is a polyhedron?

A

B

C

D

Solution

A polyhedron is a solid that has polygonal faces, straight edges and sharp corners.
Question 2
1 / -0

How many edges does a cone have?

A
0

B
1

C
2

D
3

Solution

An edge is a particular type of line segment joining two vertices .
Since a cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex, so it has no edge.
Question 3
1 / -0

Which of the following is not 3-dimensional?

A
Cylinder

B
Cone

C
Cube

D
Circle

Solution

Circle is 2-dimensional.
The other three are 3-dimensional.
Question 4
1 / -0

Which of the following will be a cross-section of a right-circular cylinder?

A
Triangle

B
Circle

C
Rectangle

D
Square

Solution

The cross-section of a right-circular cylinder is a circle.
Question 5
1 / -0

Among all the 2D shapes given below, which shape does not have corners?

A
Rectangle

B
Square

C
Circle

D
Hexagon

Solution

Circle is a round plane figure whose boundary (the circumference) consists of points, equidistant from a fixed point (the centre).
Hence, it has no corners.
Question 6

A
edges

B
vertices

C

Solution

The top view of the given figure is:
Question 9
1 / -0

Which of the following is not a cylinder?

A

B

C

D

Solution

The shape in option 3 is a hexagonal prism.
Question 10
1 / -0

We have three congruent rectangles. What do we need to make a triangular prism?

A
2 squares

B
2 equilateral triangles

C
1 circle and 1 triangle

D

Solution

We need three rectangles and two triangles to make a triangular prism.
Question 11
1 / -0

If you draw a rectangular tennis court of width 3 cm and area 21 cm²on a graph such that 1 cm in the picture is equivalent to 4 m of the original court, then what is the perimeter of the original tennis court?

A
50 m

B
60 m

C
70 m

D
80 m

Solution

Area = 21 cm²
Width = 3 cm
Area = L x W
21 cm² = L x 3 cm
L = 7 cm
According to the question,
1 cm = 4 m
So, the perimeter = 2(L) + 2(W)
= 2(7 x 4) m + 2(3 x 4) m
= 2(28) m + 2(12) m = 80 m
Question 12
1 / -0

In the given figure, places are shown with scale 1 cm : 0.2 km. If Sunil goes to school in the morning and after school, he directly goes to tuition and from tuition, he goes to playground and then after that he comes back home, then how much distance does he cover in the whole day?

A
1 km

B
2 km

C
3 km

D
4 km

Solution

Total distance covered = (5 + 5 + 5 + 5) cm = 20 cm
Since 1 cm represents 0.2 km,
So, 20 cm represents 20 x 0.2 km = 4 km.
Question 13
1 / -0

How many chocolates are there in the box?

^{_Circle_{donuts
Triangle}_{pizza slices
Rectangle}_{chocolates
Square}_{biscuit packets}}

A
2

B
3

C
4

D
5

Solution

There are four rectangles, which means chocolates.
Question 14
1 / -0

What is the ratio of the number of pizza slices to the number of biscuit packets?

^{_Circle_{donuts
Triangle}_{pizza slices
Rectangle}_{chocolates
Square}_{biscuit packets}}

A
5 : 2

B
1 : 4

C
4 : 7

D
2 : 7

Solution

5 triangles mean 5 pizza slices and 2 squares mean 2 biscuit packets.
So, the ratio is 5 : 2.
Question 15
1 / -0

^{_Circle_{donuts
Triangle}_{pizza slices
Rectangle}_{chocolates
Square}_{biscuit packets}}

A
2

B
4

C
8

D
9

Solution

The total number of triangles and circles is 9.
Hence, there are a total of 9 pizza slices and donuts.
