How many bricks would be required to edge a garden that is 37 feet long?

That would depend on the length of bricks that are used. Since the average brick is about seven inches long, I'll use that length to calculate how many bricks you will need. First, multiply the length of your garden by 12 to get the length in inches: 37 x 12 = 444 inches. Then divide the 444 by 7 (the length of the bricks) which will give you 63.43. So the number of bricks you will need (if they are 7 in long) will be 64. If the bricks are a different length, just use the same formula to calculate how many you will need, or post a message to me on my message board, and I will calculate it for you.
