Answer 1

$\bf\huge\blue{\underline{\underline{ Question : }}}$

The volume of cube with each side of length 2.1 cm is :

A) 9.261 cm³

B) 0.9261 cm³

C) 92.61 cm³

D) 926.1 cm³

$\bf\huge\blue{\underline{\underline{ Solution : }}}$

★ Given that,

• $\tt\:\rightarrow Side\:of\:cube = 2.1\:cm.$

★ To find,

• $\tt\:\rightarrow Volume\:of\:cube.$

★ Formula :

$\boxed{\rm{\red{ Volume\:of\:Cube= S^{3}}}}$

$\sf\:\implies (2.1)^{3}$

$\sf\:\implies 9.261$

# Hence,the correct option is A.

$\underline{\boxed{\rm{\purple{\therefore Volume\:of\:Cube = 9.261\:cm^{3}.}}}}\:\orange{\bigstar}$

★ More Information,

◼ TSA of Cube = 6a²

◼ LSA of Cube = 4a²

◼ Volume of Cube = S³

Answer 2

⭐ Question ?

The Volume Of A Cube With Each Side Of Length 2.1 cm is :-

[A] 9.261 cm³

[B] 0.9261 cm³

[C] 92.61 cm³

[D] 926.1 cm³

⭐ Solution :-

✔ Given :-

• Length Of Cube = 2.1 cm.

✔ To Find :-

• Volume Of Cube.

✔ Formula used :-

$\boxed{\sf{{{Volume \: Of \: Cube \: = \: {(Side)}^{3}}}}}$

Here, Side = 2.1 cm.

So,

➳ Volume Of Cube = (2.1)³

➳ Volume = 2.1 × 2.1 × 2.1 cm³

➳ Volume = 9.261 cm³

Hence, Your Answer is Option [A].
