How many bricks, each measuring 25cm*11.25cm*6cm, will be needed to build a wall 8m*6m*22.5m  Choose the correct choice from the following choices:
A) 6100	B) 6200	C) 6300	D) 6400	E) None of these
Explanation:   To solve this type of question, simply divide the volume of wall with the volume of brick to get the numbers of required bricks   So lets solve this   Number of bricks =   Volume of wall /Volume of 1 brick=800∗600∗22.5 /25∗11.25∗6=6400   Option 6400
<result>D</result>
How many bricks, each measuring 25cm*11.25cm*6cm, will be needed to build a wall 8m*6m*22.5m
