ANSWER
100
Step by step explanation:
Volume of paint = 9.375 m2 = 93750cm2
Dimensions of brick = 22.5 cm×10cm×7.5cm
Total surface area of a brick = 2(lb + bh + lh) cm2
= 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
Number of bricks can be painted = 93750/937.5 = 100
