To get straight to the point, you'll need approximately 4 sheets of 4x8 plywood to cover the floor of a 10x12 shed. Here's how we break it down:

Step-by-Step Calculation

  1. Determine The Total Area: A 10x12 shed has a floor area of 120 square feet (10 feet x 12 feet).
  2. Size Of Plywood Sheets: Standard plywood sheets are 4x8 feet, covering 32 square feet each (4 feet x 8 feet).
  3. Calculate The Number Of Sheets: Divide the total area by the area covered by one sheet of plywood.
  • 120 sq ft (total area) / 32 sq ft (per sheet) = 3.75 sheets

Since plywood is sold in whole sheets, you'll need to purchase 4 sheets.
