8 inches

the volume of a cube = s³ → ( s is the side length)

here the volume = 512 thus

s³ = 512 ⇒ s = ∛512 = 8

the length of each side = 8 inches since 8³ = 512

Let the length of each side of cube = a


volume = 512 \\ \\ \: \Rightarrow {a}^(3) = 512 \\ \\ \Rightarrow \: a = \sqrt[3]{512} = \sqrt[3]{8 * 8 * 8} \\ \\ \Rightarrow a = 8 \: inch

Length of each side is 8 inches.
