Total surface area of one brick = 2(lb + bh + lh)
= [2(22.5 ×10 + 10 × 7.5 + 22.5 × 7.5)] cm2
= 2(225 + 75 + 168.75) cm2
= (2 × 468.75) cm2
= 937.5 cm2
Let n bricks can be painted out by the paint of the container.
Area of n bricks = (n ×937.5) cm2 = 937.5n cm2
Area that can be painted by the paint of the container = 9.375 m2 = 93750 cm2
∴ 93750 = 937.5n
n = 100
Therefore, 100 bricks can be painted out by the paint of the container.
