Question

which formula is used to calculate the surface area of a cube with side length s? 4s² 2s² 6s² s³

Explanation:

Step1: Find 1 face area

Area of one square face: $A_{\text{face}} = s^2$

Step2: Count total cube faces

A cube has 6 identical square faces.

Step3: Calculate total surface area

Multiply single face area by 6: $A_{\text{total}} = 6 \times s^2 = 6s^2$

Answer:

C. $6s^2$
