Here's a quick explanation:
-
Square foot (sq ft): This is a unit used to measure area. It represents the area of a square with sides that are one foot long.
For example, if you have a floor that measures 4 feet wide and 5 feet long, the area of that floor would be 20 square feet (4 ft x 5 ft = 20 sq ft).
The cost of something typically depends on its size or area, often measured in square feet.
Here are some examples:
-
Cost of carpet: You might see carpet advertised at a price per square foot (e.g., $5 per sq ft). This means the price is based on the area of the carpet you purchase.
-
Cost of painting a room: Some painters might estimate their fees based on the square footage of the walls they need to paint.
-
Cost of new flooring: Similar to carpet, floor tiles or hardwood flooring might be priced per square foot based on the material and installation.
