Find the laternal surface area and the total surface area of a cube of edge 20cm

$\huge \bf \underline{ \underline{Answer}}$

Given:-

• Cube of edge 20cm

To Find:-

1. Lateral surface area
2. Total surface area

Calculations:-

1) Lateral surface area of a cube,

= 4 × (side)²

= 4 × (20cm)²

= 4 × 400cm²

= 1600cm²

━━━━━━━━━━━━━━━━━━━━━━━━━

2) Total surface area of cube,

= 6 × (side)²

= 6 × (20cm)²

= 6 × 400cm²

= 2400cm²
