Question

the length,breadth and thre height of a conpounding wall of ahouse are 18m,15m and 1.6m respectively.The bricks used in constructing the walls have the size 20cm×9cm×4cm.The thickness of the wall is 12 cm.Calculate the number of bricks used in the walls​

Answer 1

Explanation:

to find total volume of wall

`l * b * h`

which in this case would be

1800 x 1500 and 160 (converted to cm)

= 432 000 000

then we find the volume of each brick

20 x 9 x 4

= 720

then we divide the volume of wall by volume of each brick to find out the number of bricks used

`(432000000)/(720)`

giving us 600 000 as the answer
