How To Calculate Quantity of Blocks.

Volume of wall = L x B x H

                          = 6 x 0.152 x 3 = 2.736 cum.

Volume of One Block Without Mortar = 0.405 x 0.152 x 0.200 = 0.012312 cum.

Volume of One Block With Mortar = 0.430 x 0.152 x 0.225 = 0.014706 cum.

No of Blocks =  Volume of Wall / Volume of One Block With Mortar

                       = 2.736 / 0.014706 = 186 Nos Blocks

Volume of Total Blocks = No's of Blocks X Volume of One Block Without Mortar

                                          = 186 x 0.012312 = 2.290032 cum.    

Volume of Mortar = Total Volume - Volume of Blocks

Wet Volume = 2.736 - 2.290032 = 0.445968 cum.

Dry Volume = Wet Volume X 1.27

                      = 0.445968 x 1.27 = 0.56637936 cum

Cement Mortar Ratio = 1:6 Ratio

Cement = Ratio of Cement X Dry Volume / Sum of Ratio

             = 1 x 0.56637936 / 7 = 0.08091134 cum.

Bags = 0.08091134/0.035 = 2.31 Bags

Sand = 6 x 0.56637936 / 7 = 0.48546802 cum.

Say = 0.5 cum.
