Answer 3

\(64 = 8 \times 8 = (2 \times 2 \times 2) \times (2 \times 2 \times 2) = \)
\(= 2 \times 2 \times 2 \times 2 \times 2 \times 2 = (2 \times 2) \times (2 \times 2 )\times (2 \times 2)\)
\(= 4 \times 4 \times 4\)
\(= 4^3\)

\(V = s^3 = 4^3\)

\(\color{red}{s}^3 = \color{red}{4}^3\)

\(s = 4\)
