Question

The number of bricks of measurement 25*11.25*6cm are needed to build a wall of measurements 8m*6m*22.5cm is???

Answer 1

Hey
Here's your answer !!

The measurement of the bricks are ----->
25 cm × 11.25 cm × 6 cm .

So , the volume of each brick is ----->
= 25 × 11.25 × 6 cm³ ,
= 1687.5 cm³ .

Dimension of the wall is ----->
8 m × 6 m × 22.5 cm
= 800 cm × 600 cm × 22.5 cm .

So , the volume of the wall is ----->
= 800 × 600 × 22.5 cm³ ,
= 10800000 cm³ .

So, number of bricks required to build the wall are ------>
= 10800000 cm³ / 1687.5 cm³
= 6400 .

So , number of bricks required are 6400 . [ Answer ] .

Hope it helps !!
