Answer:
2000 bricks
Step-by-step explanation:
length of brick = 25cm
breadth of brick = 15 cm
height of brick = 10cm
volume of brick = length × breadth × height
= 25 cm × 15 cm × 10cm
= 3750 cm³
length of wall = 6m = 600 cm
breadth of wall = 0.5 m = 50cm
height of wall = 2.5 m = 250 cm
volume of wall = length × breadth × height
= 600 × 250 × 50 = 7500000 cm³
= 7500000/3750
= 750000/375
= 2000
hence, number of bricks = 2000
