Hence,25 bricks will be needed to build the wall.........

Answer 2

25 bricks of length 20 cm breadth 4 cm and height 6 CM will be needed to build a Wall of length 10 cm thickness 6 cm and height 2metre

Step-by-step explanation:

Length of brick = 20 cm

Breadth of brick = 4 cm

Height of brick = 6 cm

Volume of brick =$Length \times Breadth \times Height = 20 \times 4 \times 6 =480 cm^3$

Length of wall= 10 cm

Breadth of wall = 6 cm

Height of wall = 2 m = 200 cm

Volume of wall = $Length \times Breadth \times Height = 10 \times 6 \times 200 =12000 cm^3$

No. of bricks required = $\frac{12000}{480}=25$

Hence 25 bricks of length 20 cm breadth 4 cm and height 6 CM will be needed to build a Wall of length 10 cm thickness 6 cm and height 2metre
