Question

find the surface area of cube having the volume of 343 centimetre cube​

Answer 1

Answer:

with volume u can find side

side =7cm

then T.s.a =6a²

=6*7*7

294cm²

Answer 2

$\huge \red{ \mathfrak{solution}}$

To find :

◆ Surface Area of the cube.

Given:

◆ Volume of cube =

◆ Volume of cube =

$\boxed{ \green{\bold{343 {cm}^{3} }}}$

As we know that :

Volume of cube is

$\boxed{ \purple{ \bold{ {a}^{3} }}}$

$\leadsto \: {a}^{3} = 343 \\ \\ \leadsto \: a = \sqrt[3]{343} \\ \\ \leadsto \: a = 7$

Now ,

● Surface Area of cube =

$\boxed{ \orange{\bold{6 {a}^{2} }}}$

$\leadsto \: 6( {7}^{2} ) \\ \\ \leadsto \: 6 \times 49 \\ \\ \leadsto \: 294$

Hence, the surface area of cube is

$\huge \boxed{ \blue{294 {cm}^{2} }}$
