Question

*How many bricks of 30 cm long, 15 cm thick and 10 cm wide bricks will be enough to build a wall 24 m long, 50 cm wide and 3 m high?*

1️⃣ 8000
2️⃣ 1600
3️⃣ 1200
4️⃣ 4000​

Answer 1

Answer:

I think 1200 or 4000

Step-by-step explanation:

Answer 2

Given :

Dimensions of Brick :

• Length = 30cm
• Breadth = 15cm
• Height = 10cm

Dimensions of Wall :

• Length = 24m
• Breadth = 50cm
• Height = 3m

To Find :

• Number of bricks required to make the wall

Solution :

Making the measurement same :

⠀⟶⠀1m = 100

⠀⟶⠀24m = 100 × 24

⠀⟶⠀24m = 2400cm

Length of Wall = 2400cm

⠀⟶⠀1m = 100cm

⠀⟶⠀3m = 3 × 100

⠀⟶⠀3m = 300cm

Height of Wall = 300cm

Volume of Wall :

⠀⟶⠀Volume = Length × Breadth × Height

⠀⟶⠀Volume = 2400 × 50 × 300

⠀⟶⠀Volume = 2400 × 15000

⠀⟶⠀Volume = 3,60,00,000cm³

Volume of Brick :

⠀⟶⠀Volume = Length × Breadth × Height

⠀⟶⠀Volume = 30 × 15 × 10

⠀⟶⠀Volume = 30 × 150

⠀⟶⠀Volume = 4500cm³

Bricks required for wall :

⠀⟶⠀Volume of Wall/Volume of Brick

⠀⟶⠀3,60,00,000/4500

⠀⟶⠀3,60,000/45

⠀⟶⠀8000 bricks

So 8000 bricks will be required to make the wall
