Answer: 16 square inches
Explanation:
Apply the cube root to 64 to get [tex]\sqrt[3]{64} = 64^{1/3} = 4[/tex]
The exponent 1/3 is handy if your calculator doesn't have a cube root button.
This wooden cube has side lengths of 4 inches each.
Each square face will have an area of 4^2 = 4*4 = 16 square inches.
