Answer:
96 cm²
Explanation:
The volume (V) of a cube is calculated as
V = s³ ( s is the side length )
Here V = 64 , thus
s³ = 64 ( take the cube root of both sides )
s =
![\sqrt[3]{64}](https://img.qammunity.org/2021/formulas/mathematics/middle-school/4qa13lwkr7ioa8p8egts4vrq1vr0yloga6.png)
= 4
A cube has 6 congruent square faces.
The area of 1 face = s² = 4² = 16 cm², thus
area of 6 faces = 6 × 16 = 96 cm² ← surface area
