Question

how many bricks each measuring 25cm *11.25cm*6cm will be needed to build a wall of 8m*6m*22.5cm

Answer 1

Hello dear

Here is your answer
______________________________



Number of bricks = Area of Wall / Area of Bricks
= {(8×100 × 6×100 × 225 ×100 ) / (25 × 1125 × 6 × 10)}
= 6400

Hence,

Number of bricks to built a Wall = 6400 ans.

Answer 2

Answer:

6,40,000

Step-by-step explanation:

Dimensions of brick =(25×11.25×6)cm

=(0.25×0.1125×0.6)m

=0.0016875m

Dimensions of wall required =(8×6×22.5)m

=1080m

Number of bricks will be required=volume of wall/brick

=0.0016875/1080m

=6,40,000
