Answer 1

Answer:

(2) 2400 bricks

Step-by-step explanation:

• Length of wall = 9m = 900cm
• Hight of wall = 6m= 600cm
• Breadth or thickness of wall = 20cm

Solution:-

Volume of Wall lxbxh

$900 \times 600 \times 20 = 10800000 {cm}^{3}$

• length of brick = 30 cm
• Breadth of brock =15 cm
• Thickness of brick = 10cm

Volume of brick= lxbxh

$30 \times 15 \times 10 = 4500 {cm}^{3}$

bricks requaired for construction

$10800000 \div 4500 \\ \frac{10800000}{4500} = \frac{108000}{45} = 2400bricks$

Answer 2

Answer:

Length of the wall is 9m ×100 = 900cm

Length of the wall is 9m ×100 = 900cmBreadth of the wall is 20cm

Length of the wall is 9m ×100 = 900cmBreadth of the wall is 20cmHeight of the wall is 6m ×100= 600cm

Length of the wall is 9m ×100 = 900cmBreadth of the wall is 20cmHeight of the wall is 6m ×100= 600cmVolume of the wall = 900×20×600 = 1,08,00,000 cubic cm

Length of the wall is 9m ×100 = 900cmBreadth of the wall is 20cmHeight of the wall is 6m ×100= 600cmVolume of the wall = 900×20×600 = 1,08,00,000 cubic cmlength of the brick = 30 cm

Length of the wall is 9m ×100 = 900cmBreadth of the wall is 20cmHeight of the wall is 6m ×100= 600cmVolume of the wall = 900×20×600 = 1,08,00,000 cubic cmlength of the brick = 30 cmbreadth of the brick = 15 cm

Length of the wall is 9m ×100 = 900cmBreadth of the wall is 20cmHeight of the wall is 6m ×100= 600cmVolume of the wall = 900×20×600 = 1,08,00,000 cubic cmlength of the brick = 30 cmbreadth of the brick = 15 cmheight of the brick = 10 cm

Length of the wall is 9m ×100 = 900cmBreadth of the wall is 20cmHeight of the wall is 6m ×100= 600cmVolume of the wall = 900×20×600 = 1,08,00,000 cubic cmlength of the brick = 30 cmbreadth of the brick = 15 cmheight of the brick = 10 cmVolume of the brick = 30×15×10 = 4500 cubic cm

Therefore 10800000/4500 = 2400 bricks required
