Question

How many bricks will be required for a wall 8 m long, 6 m high and 22.5 cm
thick, if each brick measures 25 cm x 1125 cm x 6 cm?​

Answer 1

Answer:

The dimensions of the wall are Length = 8m = 800 cm Breadth = 6m = 600 cm Height = 22.5 cm We know that Volume of wall = l × b × h By substituting the values Volume of wall = 800 × 600 × 22.5 By multiplication Volume of wall = 10800000 cm3 The dimensions of brick are Length = 25cm Breadth = 11.25cm Height = 6cm We know that Volume of brick = l × b × h By substituting the values Volume of brick = 25 × 11.25 × 6 By multiplication Volume of brick = 1687.5 cm3 So the number of bricks required = Volume of wall/ Volume of brick By substituting the values Number of bricks required = 10800000/1687.5 By division Number of bricks required = 6400 Therefore, the number of bricks required to construct a wall is 6400.Read more on Sarthaks.com - https://www.sarthaks.com/719616/many-bricks-will-required-construct-wall-long-high-5cm-thick-each-brick-measures-25cm-25cm

Answer 2

Answer:

Step-by-step explanation:

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.
