Question 1
1 / -0

How many faces does a cube have?

A
$$4$$

B
$$6$$

C
$$8$$

D
None

Solution

Cube is a 3D solid object bounded by six square faces with three meeting at each vertex.
Hence a cube has $$6$$ faces.
Question 2
1 / -0

How many faces does a cuboid have?

A
$$4$$

B
$$6$$

C
$$8$$

D
None of the above.

Solution

A cuboid is a $$3-D$$ solid object bounded by $$6$$ rectangular faces, with three faces meeting at each vertex.
Hence, a cuboid has $$6$$ faces.
Question 3
1 / -0

How many pairs of congruent parallel faces does a rectangular prism have?

A
6

B
3

C
5

D
4

Solution

A rectangular prism has 3 pairs of congruent parallel faces.
Question 4
1 / -0

How many congruent faces does a cube have?

A
$$6$$

B
$$3$$

C
$$5$$

D
$$4$$

Solution

A cube has $$6$$ faces. An example of cube is a a dice where every face is numbered from one to six.
Thus a cube has $$6$$ congruent faces.
Question 5
1 / -0

Which of the following figure has six faces?

A

B

C

D

Solution

Out of the given figures, we can see that the figure in option B has $$3$$ faces visible from the front. It will have $$3$$ more faces opposite to the visible faces.

Hence, option B is correct.
Question 6
1 / -0

Cylinder has _________ curved edges.

A
4

B
2

C
3

D
1

Solution

A cylinder has two curved edges, where the cylinderical part meets the circular base and the top.
Question 7
1 / -0

What is the shape of each face of a cuboid?

A
Rectangular

B
Circular

C
Triangular

D
None of these

Solution

The face of cuboid is in the shape of a rectangle.
So, option A is correct.
Question 8
1 / -0

Is sphere, a 2D or a 3D object?

A
$$2D$$

B
$$3D$$

C
Does not exist in both planes

D
None of the above

Solution

2D shapes stand for 2 dimensional shapes. It has only two measurements that are length and breadth.
Examples for 2 dimensional objects are square, rectangle, etc.

3D shapes stand for 3 dimensional shapes. It has three measurements that are length, breadth and height.
Examples for 3 dimensional objects are cube, etc.

Therefore, a sphere is a geometrical object in perfectly round three dimensional shape similar to a round ball you might play sport with it.
Question 9
1 / -0

What is the shape of each face of a cube?

A
Square

B
Circular

C
Hyperbolic

D
Eliptical

Solution

All the edges of a cube are of equal length. All faces are square in shape.
So, option A is correct.
Question 10
1 / -0

Which of the following is the cross section of cube?

A
figure 1

B
figure 2

C
figure 4

D
figure 3

Solution

The cross section of cube is square.
