USE THIS MENU TO LOCATE MORE TIPS FOR EVERYDAY MATH  1. Add the total linear feet of footings.
2. Multiply the linear foot by the width of the footings.
3. Multiply the area by the depth of the footing.
4. Divide the Cubic Feet by 27.

Using the Formula

Using the Table

1. Identify the factor in the table based on the depth and width of the footings you are working with.
2. Multiply the Linear foot by the factor to determine how many cubic yards of concrete you will need for your footing. # CONCRETE FOR FOOTING Quantity Of Standard Block Needed For Specified SQ / FT  Determine the Number of Courses

Height (Feet) ÷ .67 & round to the next whole number

1. Add the total Linear Feet of walls to be blocked.
2. Multiply the total Linear Feet by the Height of the building to determine Area to be blocked.
3. Subtract the total square feet of all openings from the area.
4. Multiply the area by 1.125.

Example: Calculate the block needed for a wall that is 50' long, 10' high, with 80 square feet of openings.

1. 50'
2. 50' x 10' = 500 SF
3. 500 - 80 = 420
4. 420 x 1.125 = 473 (Rounded up)

Calculating the Number of Block Quantity

Block Multiplier

1. Add 3/8" Mortar joint to block dimensions           =16" x 8"=128"
2. 16" x 8" = 128"           (Face area of the block)
3. 144 / 128 = 1.125 (144 is the square foot)         1.125 Blocks per SF

Example: How many CF of mortar is needed to install 7600 Bricks? Wall thickness is 4" & the joint is 1/8".

1. Go to 1/8" (Above)
3. The multiplier is 2.9
4. 7600 / 1000 = 7.6
5. 2.9 X 7.6 = 22.04 CF of mortar.
1. Find the joint thickness.
2. Find the thickness of the wall.
3. Locate the multiplier that corresponds with step 1 & 2.
4. Divide the total amount of bricks you are installing by 1000.
5. Use the multiplier in step 3 and multiply the number from step 4. This will give you the CF of mortar needed.

Mortar for Standard Size Brick  Example:

Calculate the quantity of brick to be installed on 4000 sq/ft. You are installing a common brick with 1/4" joint. You will multiply 4000 x 7 to find that you will need 28,000 bricks.

Identify the size of your mortar joint

1. Find the number according to your brick size below.
2. Multiply your number by the area for which you will be installing the brick.
3. The result is the number of bricks you will require. Calculating Quantity of Brick

1. Add one side of the brick mortar joint to face the dimensions of the brick.
2. Multiply the Length of the brick by the Height to find the face area. (Sq Inches)
3. Divide 144 sq inches by the face area. (this is the multiplier - how many bricks you will need per sq. ft.)
4. Calculate the area of space for installing brick - Remember to minus space for openings (Doors, Windows, Ect.)
5. Multiply the area using the brick multiplier (Below).
6. Add 5-10% for waste depending on the overall size of the job.
