Find the bricks ,each 24cm× 10cm×5cm will be required for 33m long 3m high and 36 cm thick wall leaving in it 3 gate ways each 3m × 2m ?
Answers
Answer:
29550 bricks required to build the wall.
Step-by-step explanation:
Given, Length of the wall = 33m = 3300cm
Height of the wall = 3m = 300cm
Thickness of the wall = 36 cm
Volume of the wall = L × B × T = 3300 × 300 × 36
= 990000×36 = 35640000cm³
Given, Length of each gate = 3m = 300cm
Breadth of each gate = 2m = 200cm
Area of each gate = 300 × 200 = 60000cm²
No. of gates = 3
Area of 3 gates = 60000 × 3 = 180000²
Volume of the wall where bricks are required = 35640000 - 180000 = 35460000³
Given, Length of each brick = 24 cm
Height of each brick = 10cm
Thickness of each brick = 5cm
Volume of 1 brick = L×H×T = 24×10×5 = 1200cm³
Hence, No. of bricks required to build the wall = 35460000/1200 = 354600/12 = 29550 (answer).
