**How do i calculate number of bricks and cement required for a room?** For brickwork we have required number of bricks, cement and sand quantity. Find the number of bricks in 4 inch wall and calculate quantity of cement and required in 4 inch wall.

**The standard brick size in India is 190mm × 90 mm × 90mm**. And cement sand ratio in mortar is 1:6, in which one part is cement and 6 part is sand. And mortar is prepared by mix of cement, sand and water in required proportion. About 20% of dry volume of mortar water is added.

When we calculate number of bricks and cement required for a room we need several procedure, calculation and given measurement of room.

**◆ Step of calculation :-**

1) We calculate volume of brick wall in room

2) deduction of volume window and door

3) calculate volume of 1 brick with mortar

4) calculate number of bricks in all 4 sides of brick wall of room

5) calculate volume of mortar quantity

6) calculate quantity of cement required for a room

7) calculate quantity of sand required for a room

**How do i calculate number of bricks and cement required for a room?**

● take measurement of room and mortar detail

Suppose height of brick wall = 10 ft

Length of brickwall = 10 ft

Brickwork thickness = 4 inch

Mortar ratio (cement and sand) = 1:6

1 Door size in room = 4×7 sqft

1 Window size in room = 3 × 4 sqft

**● We calculate volume of brick wall in room**

Volume of 1 brick wall = (L × B × H)

Volume of 1 brick wall = 10 ft × (4/12) ft × 10 ft = 33.33 Cuft

Volume of 1 brick wall = 33.33 Cuft

Volume of 4 brick wall = 33.33 × 4 Cuft

Volume of 4 brick wall = 133.32 Cuft

**● deduction of volume window and door**

Area of 1 door = 4 × 7 sqft = 28 sqft

Area of 1 window = 3 ×4 sqft = 12 sqft

Total Area of window and door = 28 sqft + 12 sqft = 40 sqft

Volume of window and door = 40 sqft × 4/12 ft = 13.13 Cuft

Volume of window and door space covered should be deducted in total volume of brickwork required for brick wall in room

Volume of brickwork = 133.32 _ 13.33 = 120 Cuft

Volume of brickwork in Cuft = 120

We know 1 m3 = 35.3147 Cuft

Volume of brickwork in m3 = 120/35.3147

Volume of brickwork in m3 = 3.4

**● calculate volume of 1 brick with mortar**

Standard size of brick in india is known as modular brick 190 mm × 90 mm × 90 mm

Size of brick in meter = 0.19m× 0.09m× 0.09m

Volume of 1 brick in Cubic meter

= 0.19m× 0.09m× 0.09m = 0.001539m3

Suppose thickness of mortar = 10 mm

Size of brick with mortar = 200 mm×100mm×100mm

Size of brick with mortar in meter = 0.2 m× 0.1m × 0.1m

Volume of brick with mortar in m3 = 0.2 m× 0.1m × 0.1m = 0.002

**● calculate number of bricks required for construction of one room**

Total volume of brick work = 3.4 m3

Volume of 1 brick with mortar = 0.002 m3

Number of bricks = brickwork volume/Volume of 1 brick with mortar

Number of bricks = 3.4 m3/0.002m3 = 1700

Number of bricks = 1700 nos

1700 nos of bricks required for constructing a one room having size 10 feet height, 10 feet length and 4 inch thick brickwall.

**How to calculate number of bricks required for room?**

Volume of brickwork = 3.4m3

Volume of 1 brick without mortar = 0.001539 m3

Number of bricks = 1700 nos

Volume of bricks = 1700 × 0.001539 m3

Volume of bricks = 2.6163 m3

Volume of mortar = volume of brickwork _ volume of bricks

wet olume of mortar = 3.4 m3_ 2.6163m3

Wet volume of mortar = 0.7837 m3

Dry volume of mortar = 1.33 × 0.7837m3

Dry volume of mortar = 1.04 m3

**How to calculate quantity of cement required for a room?**

Mix ratio of mortar = 1:6

Total proportion = 1+ 6 = 7

Part of cement = 1/7

Part of sand = 6/7

Dry volume of mortar = 1.04m3

Density of cement = 1440 kg/m3

Quantity of cement required for constructing one room = (1/7) × 1.04 m3 × 1440 kg/m3

Quantity of cement = 214 Kg

Quantity of cement in 1 bag = 50 Kg

Number of cement bags = 214/50 = 4.3

214 Kg ( 4.3 bags ) quantity of cement required for constructing a single room having size 10 feet height, 10 feet length and 4 inch thick brickwall.

**How to calculate quantity of sand required for a room?**

Quantity of sand = 6/7 × 1.04 m3 = 0.8914m3

1 m3 = 35.3147 m3

Quantity of sand in Cuft = 0.8914 × 35.3147

Quantity of sand in Cuft = 31.5

Weight of 1 Cuft for sand = 46 Kg

Quantity of sand in kg = 46 × 31.5 Kg

Quantity of sand in Kg = 1448

0.8914m3 ( 31.5 Cuft or 1448 Kg) quantity of sand is required for constructing a single room having size 10 feet height, 10 feet length and 4 inch thick brick wall.

MEHRAN KHAN says

I want to constract 1 room 15×15ft and 1 attach bathroom 3×6 ft. So how many cement bags,sand, bricks and steel is required. Roof thickness is 5 inch.

What will be the total amount?

Vikram Singh says

Gv me total amount with attached bathroom
