(answer fast so I will mark you as brainlist)​

Answer 1

Answer:

Given :-

Dimensions of Wall :-

Length of wall = 8 m

Height of wall = 6 m

Width of wall = 22.5 m

Dimensions of bricks :-

25 cm × 11.25 cm × 6 cm

To Find :-

Number of bricks

Solution :-

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

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

Number of bricks = Volume of the walls/ Volume of one brick    

Number of bricks =  800 × 600 × 22.5 / 25 × 11.25 × 6

Number of bricks = 6400

Hence, 6400 bricks will be required to build a wall.
