Question

Find the volume of a brick whose length is 9 inch wideness is 4 inch and height is 3 inch....... and then by that brick we have to make a wall whose height is 12 feet and length is 10 feet.........

Answer 1

Answer:

1440 bricks

Step-by-step explanation:

Volume of brick

l×b×H

= 9×4×3 => 108 inch³

now volume of wall/ volume of brick = requirement of bricks

so

let the wall is of 9 inch width

as wile know that in 1 foot = 12 inch

so

12(12)×10(12)×9

114×120×9

=155520

now volume of wall/volume of brick = requirement of brick

155520/108

1440

Answer 2

Answer:

108 in³ and 1440 bricks

Step-by-step explanation:

Volume of a brick is equal to product of 3 dimensions:

9in*4in*3in= 108 in³

Volume of the wall in inches, assuming it to be 9 inch wide:

12*12in*10*12in*9in=155520 in³

Number of bricks needed:

155520 in³/108 in³= 1440 bricks
