Answer 1

Area of wall /dimensions of one brick


9375*10^4
——————-
225*75
55.55

Answer 2

☘️ Given :

• length = 22.5 cm
• breadth = 10 cm
• height = 7.5 cm

☘️ Solution :

TSA of brick = 2(lb + bh + hl)

= 2[22.5 × 10 + 10 × 7.5 + 7.5 × 22.5]

= 2[22.5 × 75 + 168.75]

= 2 × 468.75

= 937.50 cm²

No. of bricks =$\sf \dfrac{ \cancel{9.375 }\times \: 1\cancel{0} \cancel{0 }\times 100 \times 1\cancel{0 }}{\cancel{9.375} \times 1\cancel{0} \cancel{0 }\cancel{0 }}$

= 100 bricks

☘️ Answer :

• 100 bricks can be painted.
