Question 1
1 / -0

Piya glued $$4$$ white cubes together as shown. Then she painted the entire object red.
How many faces of the $$4$$ cubes were painted red?

A
$$4$$

B
$$9$$

C
$$18$$

D
$$24$$

Solution

We need to count the number of the faces outside, they will be the ones colored red.
There are $$4$$ faces each on the front, back, upper and down sides.
And $$1$$ faces each on side faces.
So there are in total $$4\times 4 + 2$$, i.e. $$18$$ faces coloured red.
Question 2

A
hexagon

B
octagon

C
heptagon

D
pentagon

Solution

We can create a pentagon by slicing a cube.
Question 4
1 / -0

What is the vertical cross-section of a solid cylindrical pipe shown in the figure?

A
An ellipse

B
A circle

C
A cylinder

D
A rectangle

Solution

The vertical cross-section of a solid cylinder is a rectangle.
Question 5
1 / -0

What two-dimensional cross-sections could we create by slicing the diagram as shown in the figure?

A
figure 1

B
figure 4

C
figure 3

D
figure 2

Solution

$$\triangledown $$ - figure 3, is the two-dimensional cross-section when we sliced the given diagram.
Question 6
1 / -0

A cross section perpendicular to the base of a cylinder give us what two dimensional shape?

A
circle

B
cone

C
rectangle

D
square

Solution

The cross-section perpendicular to the base of a cylinder given as a rectangular shape.
Question 7
1 / -0

Which geometric solid among the following has the maximum number of vertices?

A
Cone

B
Cylinder

C
Cuboid

D
Sphere

Solution

A cuboid has $$ 8 $$ vertices , which is maximum among the given solids.
Hence from the above given geometric figures, it has the maximum number of vertices.

So, $$Op-C$$
