Harry stacks several bricks, one over the other, to make a tower 114.30 centimeters high. If the height of each brick is 2.25 inches, how many bricks did Harry stack all together?

Convert the centimeters to inches--> 114.30 centimeters is 45 inches. 
Divide 45 inches by 2.25 to figure out how many bricks he stacked.
