Step-by-step explanation:

Question :-

  • Find the side of cube whose volume is 729 cm³.

To Find :-

  • Side of cube.

Solution :-

Given :

  • Volume = 729 cm³

By using the formula,

{\sf{\longrightarrow Volume\ of\ cube\ =\ a^3}}

Where,

  • a = length of the side

According to the question, by using the formula, we get :

{\sf{\longrightarrow Volume\ of\ cube\ =\ a^3}}

{\sf{\longrightarrow 729\ =\ a^3}}

{\sf{\longrightarrow \sqrt[3]{729}\ =\ a}}

{\sf{\longrightarrow 9\ =\ a}}

{\sf{\longrightarrow a\ =\ 9\ cm}}

\therefore Hence, side of cube is 9 cm.
