$\large\to{\underbrace{\underline{\sf{Understanding\:the\:concept:-}}}}$

$\implies$ Here, it is given in the question that the edges of a cube are 30 mm. Now the question has asked us to find out the surface area of the given cube.

⛤ HOW TO DO:-

$\to$ Here, to find the surface area of the given cube we need to apply the TSA formula. Then we have to put the values in the formula and then by solving it we will get the surface area of the given figure.

----------------------

ANSWER:-

❍ Surface area of the given cube is 5400 mm².

GIVEN:-

➤ Shape :- Cube

➤ Edges = 30 mm

TO FIND:-

• Here we have to find out the total surface area of the given cube.

SOLUTION:-

• We have to apply a certain formula.
• Put the values in the formula.
• Solve step by step.
• The final digits will be answer.

We know that:-

$\pink \bigstar \: \underline{\boxed{ \rm \purple{Total\: surface \: area = 6 {a}^{2} }}}$

Here,

• a = edge

----------------------

So let's solve it!

• Finding the surface area:-

$\leadsto \tt{Total\: surface \: area = 6 \times {30}^{2}}$

$\leadsto \tt{Total\: surface \: area = 6 \times 30 \times 30 }$

$\leadsto \tt{Total\: surface \: area = 6 \times 900^{2} }$

$\leadsto \tt{Total\: surface \: area = 6 \times 900^{2} = 5400^{2} }$

$\pink \ast \: \underline{\boxed{ \rm \purple{Total\: surface \: area = 5400 \: {mm}^{2} }}}$

Thus, we got the answer.
