Step-by-step explanation:

Question :-

  • Find the side of cube whose surface area is 600 cm².

To Find :-

  • Side of cube.

Solution :-

Given :

  • TSA = 600 cm²

By using the formula,

{\sf{\longrightarrow TSA\ of\ cube\ =\ 6a^2}}

Where,

  • a = length of the side

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

{\sf{\longrightarrow TSA\ of\ cube\ =\ 6a^2}}

{\sf{\longrightarrow 600\ =\ 6a^2}}

{\sf{\longrightarrow \dfrac{600}{6}\ =\ a^2}}

{\sf{\longrightarrow 100\ =\ a^2}}

{\sf{\longrightarrow \sqrt{100}\ =\ a}}

{\sf{\longrightarrow 10\ =\ a}}

{\sf{\longrightarrow a\ =\ 10\ cm}}

\therefore Hence, side of cube is 10 cm.
