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?

0%
$4$
0%
$9$
0%
$18$
0%
$24$

Explanation

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.

In which polyhedron faces are congruent regular polygons and the same number of faces meet at each vertex?

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

0%
Cone
0%
Cylinder
0%
Cuboid
0%
Sphere

Explanation

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,

Is a square prism and cube are same? explain.

0%
Yes
0%
No
0%
Depends on meausrement
0%
None of these

Explanation

${\textbf{Step -1: Defining a cube}.}$

${\text{In geometry, a cube is a three - dimensional solid object bounded by six square faces}.}$

${\text{All the faces in cube are square i}}{\text{.e}}{\text{., all the sides of cube are of same length}}{\text{.}}$

${\textbf{Step -2: Defining a square prism}.}$

${\text{A square prism is a three - dimensional cuboid where the base and top are equal squares and }}$

${\text{the remaining 4 faces may be any Quadrilateral }.}$

${\text{In square prism, the base and its opposite face are squares}.}$

${\textbf{Step -3: Comparing square prism and cube}.}$

${\text{A cube is a special type of square prism where the lengths in all three dimensions are the same}.}$

${\text{All cube are square prism, but all square prism is not cube}.}$

${\textbf{Hence, For cube and square prism to be same, the height of square prism must }}$

${\textbf{be equal to length of its base. Thus, option C is correct}.}$

Identify the following 3-D object.

0%
cylinder
0%
right rectangular prism
0%
right triangular prism
0%
triangular pyramid

Explanation

The given 3-D object has all six faces as rectangles.

This is a polyhedron that has

$8$ vertices,

$12$ edges, and

$6$ faces.

All the properties of the above 3-D object match with the properties of a right rectangular prism.

Hence, the given 3-D object is a right rectangular prism.

The faces of a square pyramid consist of:

0%
Six squares
0%
Two squares and four rectangles
0%
One square and three triangles
0%
One square and four triangles

Explanation

The square pyramid has a square base.

And the faces attached with apex are triangles.

From each side of square, one triangle face is being created and get attached to apex.

Since, there are

$4$ sides in a square.

Thus, there will be

$4$ triangles.

Hence, faces of a square pyramid has one square and four triangles.

The faces of a triangular pyramid consist of:

0%
Two triangles and three rectangles
0%
Two rectangles and three triangles
0%
One square and three triangles
0%
Four triangles

Explanation

The triangular pyramid has a triangle base.

And other faces attached with apex are triangles.

With every side of base, one triangle face is being created and gets attached to apex.

So, there will be

$3$ triangles faces except base.

Hence, faces of a triangle pyramid consists of four triangles.
