Rectangular Prism (Box) Formulas
Volume
V = l × w × h
Surface Area
SA = 2(lw + lh + wh)
Space Diagonal
d = sqrt(l² + w² + h²)
The space diagonal runs from one corner to the opposite corner through the interior of the box.
Example Calculation
Box with length 10, width 5, height 3.
- 01Volume = 10 × 5 × 3 = 150
- 02Surface area = 2(50 + 30 + 15) = 2 × 95 = 190
- 03Diagonal = √(100+25+9) = √134 ≈ 11.5758
