Answer 1

Here is ur awesome answer mate...

length of brick = 25cm

breadth of brick = 15 cm

height of brick = 10cm

volume of brick = length × breadth × height

= 25 cm × 15 cm × 10cm

= 3750 cm³

length of wall = 6m = 600 cm

breadth of wall = 0.5 m = 50cm

height of wall = 2.5 m = 250 cm

volume of wall = length × breadth × height

= 600 × 250 × 50 = 7500000 cm³

number of bricks = $\frac{volume- of -wall}{volume - of - brick}$

= 7500000/3750

= 750000/375

= 2000

hence, number of bricks = 2000

Answer 2

Answer:

2000 brick ate requried to make wall

Step-by-step explanation:

volume of each brick =25 x 15 x 10 = 3750cm

volume of the wall = 6 x 2.5 x 0,5 =.

7.5m

number of brick requride(n)=.

vol of wall. 7.5x 1000000 = 2

vol of brick. 3750
