Question

how many bricks are required to build a wall 15 m long 3 m high and 50 cm thick ,if each brick measures 25 cm by 12 cm by 6 cm?

Answer 1

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
