A) 6080
B) 3040
C) 1520
D) 12160
Correct Answer: A
Solution :
(a): Volume of wall \[=1200\times 500\times 25\]\[=15000000\,\,c{{m}^{3}}\] Volume of cement \[=5\text{ }%\text{ }of\text{ }15000000\]\[=750000\text{ }c{{m}^{3}}\] Remaining volume \[=15000000-750000\]\[=14250000\text{ }c{{m}^{3}}\] Volume of a brick \[=25\times 12.5\times 7.5=2343.75\,\,c{{m}^{3}}\] Number of bricks used \[=\frac{14250000}{2343.75}=6080\]You need to login to perform this action.
