How to Calculate Brick, Cement, and Sand Quantity for a 10x10 Room

Introduction

Planning brickwork for a 10×10 room? You need to know how many bricks, cement bags, and sand to order. This guide walks you through the calculation with formulas and a worked example. Use our free brick calculator for instant results—it has a 10×10×10 ft room preset for quick estimates.

Standard Assumptions

• Room size: 10 ft × 10 ft floor, 10 ft height
• Wall thickness: 9 inches (common for external/load-bearing walls)
• Brick size (India): 190 mm × 90 mm × 90 mm (with mortar: 200 × 100 × 100 mm)
• Mortar ratio: 1:6 (cement : sand)
• Wastage: 10%

Formula for Brick Quantity

Step 1: Wall Area

For a rectangular room, total wall area:

Wall area = 2 × (Length × Height + Width × Height)

For 10×10×10 ft room:

• Length = 10 ft, Width = 10 ft, Height = 10 ft
• Wall area = 2 × (10×10 + 10×10) = 2 × 200 = 400 sq ft

Step 2: Wall Volume

Wall volume = Wall area × Wall thickness

• 9-inch wall = 0.75 ft
• Volume = 400 × 0.75 = 300 cubic ft = 8.5 m³ (approx)

Step 3: Number of Bricks

Single brick volume (with mortar) = 0.2 m × 0.1 m × 0.1 m = 0.002 m³

Bricks = (Wall volume / Brick volume) × 1.1 (wastage)

• Bricks = (8.5 / 0.002) × 1.1 ≈ 4,675 (in cubic meters)

Note: The actual formula uses mortar volume separately. Our brick calculator uses industry-standard methods.

Approximate Result for 10×10×10 ft, 9" Wall

Material	Quantity
Bricks	~1,500–1,600
Cement (50 kg bags)	~35–40 bags
Sand	~2–2.5 m³

Use the brick calculator with the 10×10×10 ft preset for exact numbers.

Cement and Sand (Mortar) Calculation

For 1:6 cement-sand mortar:

• Cement: 1 part of total 7 parts → (Mortar volume / 7) × density
• Sand: 6 parts of total 7 parts

Mortar volume ≈ 30% of brickwork volume for 9" wall.

Our cement calculator and sand calculator can help verify quantities.

Use the Brick Calculator

1. Go to Brick Calculator
2. Click "10×10×10 ft room" preset
3. Select wall thickness (9 inches for external walls)
4. Click Calculate

You'll get exact bricks, cement bags, and sand in m³.

Tips for Ordering Materials

1. Add 5–10% extra for breakage and cutting
2. Order cement in batches – store properly to avoid moisture
3. Verify sand quality – use river sand or approved M-sand
4. Track consumption – use material tracking during construction to avoid over-ordering
