A) 12960
B) 14420
C) 24566
D) 14296
Correct Answer: A
Solution :
Volume of the wall \[=24\times 0.4\times 6=57.6{{m}^{3}}\] Volume of mortar \[=\frac{57.6}{10}=57.6\,{{m}^{3}}\] Volume of used bricks \[=(57.6-5.76){{m}^{3}}=51.84{{m}^{3}}\] Volume of each brick \[(25\times 16\times 10)c{{m}^{3}}=4000c{{m}^{3}}\] \[=\frac{4000}{100\times 100\times 100}\,\,{{m}^{3}}=\frac{4}{1000}{{m}^{3}}\] \[\therefore \] Number of bricks used \[=\frac{51.84}{\frac{4}{1000}}=12960\]
