Question

4. How many bricks will be
required to build a wall of 8 m
long, 6 m height and 22.5 cm
thick if each brick measures 25
cm by 11.25 cm by 6cm?​

Answer 1

Answer:

8m = 800cm

6m = 600cm

22.5 cm = 22.5 cm

volume of wall / volume of bricks

800× 600 × 22.5 / 25× 11.25× 6

10800000 / 1687.5 = 6400

6400 BRICKS ARE REQUIRED TO MAKE A WALL OF 8m, 6m , 22.5 cm

Answer 2

Answer:

Volume of wall = (800 × 600 × 22.5) cm cube

volume of bricks =( 25 × 11.25 × 6) cm cube

required no. of bricks =

(800×600×22.5)/(25 ×11.25×6)

10800000/1687.5

= 6400 bricks
