Question

How many bricks will be required to construct a wall 10 m long 4 m wide 3 m high if each brick measures 25x12x8 cm

Answer 1

volume of wall=1000×400×300 cm³,

volume of each brick=25×12×8 cm³,

then
number of bricks=(1000×400×300)/(25×12×8),

=10000000/200,

=50000

Answer 2

50000 bricks will be required to construct a wall 10 m long 4 m wide 3 m high if each brick measures 25x12x8 cm

Step-by-step explanation:

Length of wall = 10 m = 1000 cm

Breadth of wall = 4 m = 400 cm

Height of wall = 3 m = 300 cm

Volume of wall = $1000 \times 400 \times 300 = 120000000 cm^3$

Length of brick = 25 cm

Breadth of brick = 12 cm

Height of brick = 8 cm

Volume of brick =$25 \times 12 \times 8 = 2400 cm^3$

No. of bricks =$\frac{120000000}{2400}=50000$

Hence  50000 bricks will be required to construct a wall 10 m long 4 m wide 3 m high if each brick measures 25x12x8 cm
