Standard modular brick = 6.85 units/sq ft with 3/8" joint

Calculated Output Metrics

Bricks to Order (5% Waste) 1,151 bricks
Total Wall Face Area 160.0 sq ft
80 lb Mortar Bags (Type N) 8 bags (1 per 140 bricks)
Masonry Sand Required 0.77 tons

Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
Modular Bricks = Wall Area (sq ft) × 6.85 Bricks/sq ft

Step-by-Step Mathematical Derivation

1
Wall Surface Calculation

Wall Face Area A = Wall Length × Wall Height.

2
Brick Density with Standard 3/8" Mortar Joint

A standard modular brick (3-5/8" × 2-1/4" × 7-5/8") with 3/8" joint yields 6.85 bricks per square foot: Bricks = ceil[A × 6.85 × 1.05].

3
Mortar Consumption Heuristic

One 80 lb bag of pre-mixed masonry mortar lays approximately 125 to 140 modular bricks.

Frequently Asked Questions

What is the difference between Type N and Type S mortar? +
Type N mortar (medium strength, ~750 psi) is ideal for exterior above-grade brick veneer. Type S mortar (high strength, ~1,800 psi) is required for below-grade foundations or structural walls.
How many bricks come on a standard delivery cube/pallet? +
A standard brick pallet (cube) contains 500 to 525 modular bricks and weighs approximately 2,000 to 2,400 lbs.
