Question

the volume of a cube is 729cm^3 find its length​

Answer 1

Answer:

Volume of a cube = side × side × side

Side^3

then in the question give the volume of cube is 729 and find the length

as we know length of cube = side of a cube

then, 729= side^3

side(length) = √729

= 9

Answer 2

➵ Given :-

• Volume of cube = 729 cm³

➵ To Find :-

• Find the side .

➵ Solution :-

${\red{❒}}{\underline{\bf{ We \: know \: that :}}}$

${\large{\red{\bigstar \: \: {\blue{\underbrace{\underline{\orange{\bf{Volume_{(Cube)} = a³ }}}}}}}}}$

${\red{❒}}{\underline{\bf{Here :}}}$

• A = Side

${\red{❒}}{\underline{\bf{Side :}}}$

${\large{:{\longmapsto{\bf{Volume = a³}}}}}$

${\large{:{\longmapsto{\bf{ \: \: \: \: \: \: \: \: \: \: \: \: \: 729 = a³}}}}}$

${\large{:{\longmapsto{\bf{ \: \: \: \: \: \: \: \: \: \: \: \: \: a = \sqrt{729} }}}}}$

${\large{\purple{:{\longmapsto{\overline{\underline{\boxed{\bf{A = Side = 9 cm}}}}}}}}}$

${\red{❒}}{\underline{\bf{ Therefore :}}}$

${\large{\orange{\underline{\green{\underline{\red{\pmb{\mathfrak{ Side \: of \: the \: cube \: is \: 9 \: cm .}}}}}}}}}$
