Formula Used in Sq Feet Calculation
The Sq Feet Calculator uses a very simple mathematical formula:
Basic Formula:
Area = Length × Width
If quantity is included:
Total Area = Length × Width × Quantity
Example Calculation:
Suppose:
- Length = 12 feet
- Width = 10 feet
- Quantity = 2
Step 1:
Area of one unit:
12 × 10 = 120 sq ft
Step 2:
Multiply by quantity:
120 × 2 = 240 sq ft
Final Answer:
Total Area = 240 square feet
