Question

suppose that there are two cubes having edges 2 cm and 4 cm respectively.Find the volume of cubes.

Who will put correct answers i will mark as Brainliest ​

Answer 1

Answer:

area of cube with side 2cm : 2*2*2

= 8 CM cube

area of cube with side 4cm : 4*4*4

=64 CM cube

Answer 2

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\tt{\therefore{Volume(1)=8\:cm^{3}}}}$

$\green{\tt{\therefore{Volume(2)=64\:cm^{3}}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{ \underline \bold{Given: }} \\ \tt{: \implies Edge \: of \: cube \: first( a_{1}) = 2 \: cm} \\ \\ \tt{: \implies Edge \: of \: cube \: second( a_{2}) = 4 \: cm} \\ \\ \red{ \underline \bold{To \: Find: }} \\ \tt{: \implies Volume \: of \: both \: cubes = ?}$

• According to given question :

$\bold{As \: we \:know \:that} \\ \tt{: \implies Volume \: of \: cube = { a_{1}}^{3} } \\ \\ \tt{: \implies Volume \: of \: cube = {2}^{3} } \\ \\ \tt{: \implies Volume \: of \: cube = 2 \times 2 \times 2} \\ \\ \green{\tt{: \implies Volume \: of \: cube = 8 {cm}^{3} }} \\ \\ \bold{As \: we \:know \:that} \\ \tt{: \implies Volume \: of \: cube = { a_{2}}^{3} } \\ \\ \tt{: \implies Volume \: of \: cube = {4}^{3} } \\ \\ \tt{: \implies Volume \: of \: cube = 4 \times 4 \times 4} \\ \\ \green{\tt{: \implies Volume \: of \: cube = 64{cm}^{3} }} \\ \\ \purple{\bold{Some \: formula \: related \: to \: topic}}\\ \\ \pink{ \circ \: \tt{T.S.A \: of \: cube = 6 {a}^{2} }} \\ \\ \pink{ \circ \: \tt{C.S.A \: of \: cube = 4{a}^{2} }}$
