Question

The volume of a cube is 9261cm find the side of yhe cube

Answer 1

Suppose that the side of a cube is 'a' then a^3=9261 then a=21

Answer 2

Step-by-step explanation:

Question :-

• Find the side of cube whose volume is 9,261 cm³.

To Find :-

• Side of cube.

Solution :-

Given :

• Volume = 9,261 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 :

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

${\sf{\longrightarrow 9,261\ =\ a^3}}$

${\sf{\longrightarrow \sqrt[3]{9,261}\ =\ a}}$

${\sf{\longrightarrow 21\ =\ a}}$

${\sf{\longrightarrow a\ =\ 21\ cm}}$

$\therefore$ Hence, side of cube is 21 cm.
