## Chapter 2 Project: The Bricklayer's Formula

## My Steps

I chose "The Bricklayer's Formula" as my chapter two project. The goal of this project was to figure out if the formula N=7LH would work for different samples of the same brick wall. If it didn't work, I should suggest a formula that does work.To carry out the project, I went to a brick wall and measured four parts of it. The formula suggested by my math book is: N=7LH (all measurements are in feet). I placed my measurements of length and height in the positions of L and H, to see if the real number of bricks matched the outcome of the formula.

Sample 1: N=7*3.3*6.6 N=152.46 Real count=2oo bricks.

Sample 2: N= 7*3.3*3.3 N=76.23 Real count=40 bricks.

Sample 3: N= 7*1.6*1.6 N=17.92 Real count =20 bricks.

Sample 4: N= 7*0.6*0.6 N= 2.52 Real count= 6.25

The formula is correct, but you have to count the gap between the bricks on the wall. The formula I came up with is N=LH/ the size of the bricks.

The area of the brick wall depends on the length and height and with the formula you can calculate how many bricks you need. During the project, it was very interesting to find out you always have to remember to calculate the distance between the bricks. It's not enough to count the bricks, you also have to include the gap between between them.
