Answer 1

120 stick. This is your answer

Answer 2

Answer:

120

Step-by-step explanation:

Matchsticks:

Length = 6 cm.

Breadth = 4.5 cm.

Height = 2 cm.

Volume = l * b * h

             = 6 * 4.5 * 2

             = 54 cm³.

Wall:

Length = 18 cm.

Breadth = 18 cm.

Height = 20 cm.

Volume = l * b * h

             = 18 * 18 * 20

             = 6480.

Number of matchsticks:

= 6480/54

= 120.

Hope it helps!
