Answer:

9 cm

Step-by-step explanation:

We know that

cube's volume = edge³

So

edge³ = cube's volume

= cube's volume

 =  >  {a}^{3}  = 729 {cm}^{3}  \\   =  > \sqrt[3]{ {a}^{3} }  =  \sqrt[3]{ {729cm}^{3} }  \\  =  > a =  \sqrt[3]{729}   \: cm  \\  =  > a =  \sqrt[3]{9 \times 9 \times 9}  \: cm \\  =  > a =  \sqrt[3]{ {9}^{3} }  \: cm \\  =  > a = 9cm

a = arm (edge, side) of cube

hope it helps.
