Answer» Answer: 6250 Step-by-step EXPLANATION: Measurement of the WALL Length of wall= 15m =15×100 =1500 Height of wall = 3M = 3× 100 =300 Thickness of wall= 25 Volume of wall = length × breath × height 1500 × 300 × 25
= 11250000
Measurement of brick Length= 25, breadth=12 and height=6 Volume of brick = 25 × 12 × 6 = 1800 Total no of bricks = volume of wall ÷ volume of 1 brick 11250000÷1800 = 6250 |
