Question

How many bricks, each measuring 25cm by 11.25cm by 6cm will be needed to build a wall 8m by 6m by 22.5m

Answer 1

Hey there! ☺☻☺

Dimensions of brick = 25 cm , 11.25 cm , 6 cm
Volume of brick = 25 * 11.25*6 cm³

Dimensions of wall = 8m , 6 m, 22.5 m
                                = 800 cm, 600 cm , 2250 cm
Volume of wall = 800*600*2250 cm³

Now, Bricks required  = volume of wall / volume of brick
                                   = 800 * 600 * 2250 / 25 * 11.25 * 6
                                   = 1080000000 / 1687.5
                                   = 640000

Hence, no. of bricks required = 640000

Hope It Helps You! ☺☻☺

Answer 2

Hey!

____________________________

Length of the brick = 25 cm
Breath of the brick = 11.25 cm
Height of the brick = 6 cm

Volume of the brick = lbh
Volume = 25×11.25×6
Volume = 1,687.5 cm^3

Length of the wall = 8 m = 800 cm
Breath of the wall = 6 m = 600 cm
Height of the wall = 22.5 m = 2250 cm

Volume of the wall = lbh
Volume = 800×600×2250
Volume = 10,80000000 cm^3

Number of bricks needed to make the wall=

Volume of wall / Volume of brick
= 10,80000000/1,687.5

Number of bricks required = 640,000
