Assuming:-

Volume of brickwork = 1m³

Size of brick—>19x9x9 cm

Thickness of mortar = 10mm (1cm)

### Quantity of Bricks:-

** No. of bricks = Volume of brickwork/ volume of 1 brick with mortar**

Volume of 1 Brick with mortar = 0.20×0.10×0.10=0.002 m³

∴ No. of bricks = 1/0.002 = **500 ****No’s**

**Quantity of cement:-**

Volume of bricks= (0.19×0.09×0.09) x 500 = 0.001539 x 500 = 0.7695 m³

**Quantity of mortar = Quantity of brickwork – Volume of bricks**

Quantity of mortar = 1 – 0.7695 = 0.2305 m³

**Mix Ratio –> 1:6**

**Dry volume of mortar = Wet volume x 1.33**

Dry Volume = 0.2305 m³x 1.33 = 0.3066 m³

**Quantity of Cement = {(Dry Volume of mortar x Cement ratio) / (Sum of the ratio)}**

∴Quantity of cement = (0.3066 x 1) /(1+6)=0.0438 m³

**Density of Cement = 1440 kg/m****³**

∴ Weight of Cement = 1440 x 0.0438 = 63.072Kg

**1 bag of cement contains 50 kg of cement **

∴ Number of bags = 63.072 Kg / 50 kg = **1.261 No’s**

** Quantity of Sand:-**

** Cement : Sand :: 1:6**

**Quantity of Sand = Quantity of Cement x 6**

∴ Quantity of Sand = 0.0438m³x6= **0.2628 ****m³**

**1 m³=35.3147 Cubic Feet (CFT)**

∴ Quantity of sand = 0.2628 x 35.3147 = 9.280 CFT

**Density ****of sand = 1920 kg/m³**

∴ Weight of the sand= 0.2628 x 1920= 504.576 kg =>0.504 tonnes

**Material Cost:-**

**Labour ****Cost:-**

**Area=volume/thickness**** = 1m³/0.20m = 5m²**

**Summary:-**

Cost of material = Rs. 3271.13

Cost of labours = Rs. 3237.5

Sum of labour & material cost= **Rs****. 6508.63 **

Add:-

1.Water charge **@ 1.5% **= (1.5/100)x6508.63 = **Rs****. 97.629**

2.Contractor’s profit **@15 % **= (15/100)x6508.63= **Rs****. 976.294**

**Total cost = 97.532 + 975.323+6502.15 = ****Rs****. 7582.553**

So, Cost of brickwork may vary from** Rs. 6000 to 8500** based on location
