(C) To find the number of bricks,we divide the volume of the wall by the volume of a single brick.First,convert all dimensions of the wall into centimeters:Length of the wall $= 15\, m = 1500\, cm$Height of the wall $= 3\, m = 300\, cm$Thickness of the wall $= 50\, cm$Volume of the wall $= 1500\, cm 	imes 300\, cm 	imes 50\, cm = 22,500,000\, cm^3$Volume of one brick $= 25\, cm 	imes 12\, cm 	imes 6\, cm = 1800\, cm^3$Number of bricks $= \frac{	ext{Volume of the wall}}{	ext{Volume of the brick}} = \frac{22,500,000}{1800} = 12500$.

How many bricks are required to build a $15\, m$ long,$3\, m$ high,and $50\, cm$ thick wall,if each brick measures $25\, cm \times 12\, cm \times 6\, cm$?
