Calculations

Example 1: Open Box

Step Calculation
Box Type Open
Length 5 cm
Width 3 cm
Height 2 cm
Surface Area (5 × 3) + (2 × 5 × 2) + (2 × 3 × 2) = 46 cm²

In this example, an open box with dimensions 5 cm by 3 cm by 2 cm has a surface area of 46 cm².

Example 2: Closed Box

Step Calculation
Box Type Closed
Length 4 m
Width 2 m
Height 3 m
Surface Area 2 × (4 × 2) + 2 × (4 × 3) + 2 × (2 × 3) = 52 m²

For a closed box with dimensions 4 m by 2 m by 3 m, the surface area is calculated to be 52 m², providing an accurate measure for construction or packaging needs.
