How to approach surface area
Surface area is the total area of every exterior face of a three-dimensional figure. A net helps organize faces and shows which dimensions belong to each area calculation.
Unlike volume, surface area uses square units. Count every face once and combine areas only after labeling them.
Learning objectives
- Find surface area from dimensions
- Use nets to organize faces
- Distinguish surface area from volume
Skills to review first
- Area formulas
- Three-dimensional figure vocabulary
- Multiplication
Worked example
Follow the reasoning step by step
Find the surface area of a 4 cm by 3 cm by 2 cm rectangular prism.
- Use SA = 2(lw + lh + wh).
- Compute face areas: 12, 8, and 6.
- Add 12 + 8 + 6 = 26.
- Double for opposite faces.
Solution: 52 cm².
