**Block**

Length of wall X Height of wall = Square footage of wall

Square footage of wall X 1.125 = Number of block required

Example: 120' X 24' = 2,880 Sq. Ft. X 1.125 = 3,240 block

**Modular Block**

Square footage of wall X 7.00 = Number of brick required

Example: 120' X 24' = 2.880 Sq.Ft. X 7.00 = 20,160 Brick

**Masonry Cement**

30 Bags of masonry cement per thousand block

Example: 3,240 divided by 1,000 = 3.24 X 30 = 97.2 (98 bags)

8.5 Bags of masonry cement per thousand brick

Example: 20,160 divided by 1,000 = 20.16 X 8.5 = 171.36 (172 bags)

**Masonry Sand**

3.5 Tons of sand per thousand block

Example: 3,240 divided by 1000 = 3.24 X 3.5 = 11.34 tons

1 Ton of sand per 1000 brick

20,160 brick divided by 1,000 = 20.16 tons

**Wall Reinforcing**

Number of Block X 1.34 divided by 2 = Lineal Feet at 16" OC (Every 2 courses)

Number of Block X 1.34 divided by 3 = Lineal Feet at 24" OC (Every 3 courses)

**Block Fill**

12" Block - Number of Block X .37 divided by 27 X 1.05 = Cu. Yds.

8" Block - Number of Block X .28 divided by 27 X 1.05 = Cu. Yds

6" Block - Number of Block X . 26 divided by 27 X 1.05 = Cu. Yds.

**Masonry Fill Insulation**

12" Block - 13 - 4 cu. Ft. Bags per 100 Sq. Ft. of wall

8" Block - 7 - 4 cu. Ft. Bags per 100 Sq. Ft. of wall
