How many bricks, each of dimensions 18 cm by mbyll​

Answer 1

Answer:

Number of bricks = 25000.

Explanation:

Volume of a brick = l*b*h

Volume of the wall = l*b*h

Number of bricks needed = Volumes of $\frac{Wall}{Brick}$

= $\frac{1500 * 125 * 250 }{25 * 7.5 * 10}$ (convert all values into centimeter)

= 25000 bricks
