Question

How many bricks each measuring (25 cm × 11.25 cm × 6 cm) will be required to construct a wall (8 m × 6 m × 22.5 cm)?

पर्याय

• 8000

• 6400

• 4800

• 7200

Answer 1

6400

Explanation:

Volume of the wall = (800 × 600 × 22.5) cm³

Volume of each brick = (25 × 11.25 × 6) cm³ 

Number of bricks `= "Volume of the wall"/"Volume of each brick "`

`= (800xx600xx22.5)/(25xx11.25xx6)`

= 6400
