Answer 2

Given :- While cleaning the house before Deepawali, Kiran found few wooden blocks of different shapes. Inspite of throwing it he thought of making another shape by joining these shapes. One such solid shape which Kiran made is given below.

To Find :-

(i) Name the two solid shapes joined by Kiran to form the given solid.

(ii)Write the total number of faces, edges and vertices in the solid.

(iii) Verify Euler's formula for the solid.

Solution :-

from image we can see that,

→ The two solid shapes joined by Kiran to form the given solid are = Pyramid + Cuboid . (Ans.i)

now,

• Total number of faces of solid = 9 .
• Total number of edges of solid = 16 .
• Total number of vertices of solid = 9 .

therefore, Euler's formula says that,

→ F + V - E = 2

→ 9 + 9 - 16 = 2

→ 18 - 16 = 2

→ 2 = 2 (Hence, verified .) (Ans.iii)
