Calculation at Cost of the Brick

                    M3, Weight                      = Volume x Density

                           Weight of cement    = 28.914 x 1430   = 41,347.42Kg

                           Weight of sand        = 57.829 x 1548   = 89,520.84Kg

                           Weight of dry paper = 46.263 x 120  = 5,551.56Kg

                          Cost of cement        = weight x (cost / Kg) 

                                                          = 41,347.42 x 3.5

                                                          = Rs1 44,715.97

                          Cost of sand                     = weight x (cost / Kg) 

                                                          = 89,520.84 x 0.5

                                                          = Rs44,760.42

                     

     Cost of Dry paper                        = weight x (cost / Kg) 

                                                         = 5,551.56 x 1

                                                         = Rs5,551.56

                   

                    Total cost of materials for 1 lakh brick = Rs1,95,027.95 

                    Labour and production cost                = 10% x 1,95,027.95

                                                                                = 19,502.795

                    Total cost for 1 lakh brick                   = Rs2,14,530.75

                   

                    Cost of 1 brick                                   = Total cost /  1,00,000

                                                                              = 2,14,530.75 / 1,00,000

                                                                               = Rs2.15
