How many bricks each of dimensions 18 cm by 12cm by 10cm will be required to build a wall 12 m long, 80cm thick and 3.6m high?find the total cost of bricks at rs750 per 1000
Answers
Answer:
Step-by-step explanation:
Let x bricks are required
Therefore, volume of x bricks =volume of wall
X×18cm ×10cm×12cm
16000 bricks each of dimensions 18 cm by 12 cm by 10 cm will be required to build a wall 12 m long, 80 cm thick and 3.6 m high and the total cost of bricks will be Rs. 12000.
Step-by-step explanation:
Step 1:
Dimensions of each brick:
Length = 18 cm = 0.18 m
Breadth = 12 cm = 0.12 m
Height = 10 cm = 0.1 m
∴ The volume of each brick = length * breadth * height = 0.18 * 0.12 * 0.1 = 2.16 * 10⁻³ m³
Step 2:
Dimensions of the wall:
Length = 12 m
Breadth = 80 cm = 0.80 m
Height = 3.6 m
∴ The volume of the wall = length * breadth * height = 12 * 0.8 * 3.6 = 34.56 m³
Step 3:
Therefore,
The no. of bricks required for building the wall is given by,
= [volume of the wall] / [volume of each brick]
= [34.56] / [2.16 * 10⁻³]
= [34.56*10³] / [2.16]
= 16000
Now, the cost of 1000 bricks is given as Rs. 750
∴ The total cost of 16000 bricks will be = [750/1000] * 16000 = Rs. 12000.
Thus, 16000 bricks are required to build the wall and the total cost of the bricks will be Rs. 12000.
