Example: Calculating Paint for a Room

Scenario: You have a room measuring 15 feet long, 12 feet wide, with a wall height of 10 feet. You have 1 door and 2 windows, want 2 coats, paint coverage is 400 sq ft per gallon, paint costs $35 per gallon, and primer is needed at $25 per gallon.

Steps:

  1. Wall Area = 2 × (15 + 12) × 10 = 540 sq ft
  2. Subtract door and window area: 1 door × 20 + 2 windows × 15 = 50 sq ft
  3. Paintable Area = 540 − 50 = 490 sq ft
  4. Total Area to Paint = 490 × 2 coats = 980 sq ft
  5. Paint Gallons Needed = 980 ÷ 400 = 2.45 → 3 gallons (round up)
  6. Paint Cost = 3 × $35 = $105
  7. Primer Gallons Needed = 490 ÷ 400 = 1.225 → 2 gallons
  8. Primer Cost = 2 × $25 = $50
  9. Total Cost = $105 + $50 = $155

This quick calculation ensures you buy the right amount of paint and primer.
