the measurement of a brick is 20 cm by 12 cm by 8 cm. Find its volume. Also find the number of such bricks that will be required to construct a wall 16.8m height, 2.5m wide and 12cm thick.
Answers
Volume of brick = l * b* h
= 20 * 12 * 8
=1920 cm³
1 m = 100 cm 16.8m = 168 * 100 cm
2.5 m = 2.5 * 100 cm
Volume of wall = 16.8 *100 * 2.5*100 * 12
= 5040000 cm ³
No. of bricks required to construct the wall = 5040000/1920
= 2625 bricks
Answer:
Volume of brick = l * b* h
= 20 * 12 * 8
=1920 cm³
1 m = 100 cm 16.8m = 168 * 100 cm
2.5 m = 2.5 * 100 cm
Volume of wall = 16.8 *100 * 2.5*100 * 12
= 5040000 cm ³
No. of bricks required to construct the wall = 5040000/1920
= 2625 bricks
