Answer 1

Correct Question:-

• The volume of a cubical box 216 cm³.Find its side ?

AnswEr :-

• $\boxed{\purple{\sf{\star{The\:Side\:of\:cubical\:box\:is\:-:6 \: cm }}}}$

Explanation:-

☆ Figure related to the question:-

$\setlength{\unitlength}{4mm}\begin{picture}(10,6)\thicklines\put(0,1){\line(0,1){10}}\put(0,1){\line(1,0){10}}\put(10,1){\line(0,1){10}}\put(0,11){\line(1,0){10}}\put(0,11){\line(1,1){5}}\put(10,11){\line(1,1){5}}\put(10,1){\line(1,1){5}}\put(0,1){\line(1,1){5}}\put(5,6){\line(1,0){10}}\put(5,6){\line(0,1){10}}\put(5,16){\line(1,0){10}}\put(15,6){\line(0,1){10}}\put(4.6,-0.5){\bf\large 6 cm}\put(13.5,3){\bf\large 6 cm}\put(-4,5.8){\bf\large 6 cm}\end{picture}$

Given :-

• The volume of a cubical box 216 cm³

To Find :-

• The side of cubical box .

Solution:-

• $\boxed{\blue{\sf{\star{Volume \:of\:Cube\:-:side \times side \times side }}}}$

Or ,

$\boxed{\blue{\sf{\star{Volume \:of\:Cube\:-:side³ }}}}$

Here ,

• Side of a cube or cubical box -: ??
• Volume of a cube or cubical box -: 216 cm³

Now ,

$\pink{\sf{\rightarrow { 216 = side³ }}}$

$\pink{\sf{\rightarrow { \sqrt[3]{ 216} = side }}}$

$\pink{\sf{\rightarrow { 6 cm = side }}}$

Therefore:-

$\boxed{\purple{\sf{\star{Side\:-:6c \: cm }}}}$

Hence ,

$\boxed{\purple{\sf{\star{The\:Side\:of\:cubical\:box\:is\:-:6 \: cm }}}}$

Answer 2

Answer:

Let the side of a cube is a cm

Given volume of a cube is 216 cm³

⟹a³ =216

⟹a=6

Surface area of cube is 6a² =6×6²

=216 cm ²
