Can someone please work out the area. and if you get it correct I will mark u as the brainiest. thank you. Thank you

Answer 1

Given :-

Length of each side of a cube, a = 0.7 m

To Find :-

The TSA of the cube in square centimetres.

Solution :-

We know for a cube,

$\boxed{\mathbf{\color{red}{TSA=6a^2}}}$

Putting the values :-

$\sf{\longrightarrow TSA = 6\times(0.7)^2}\\\\\sf{\longrightarrow TSA=6\times0.49}\\\\\sf{\longrightarrow TSA=2.94\ m^2}$

________________

Converting 2.94 m² to cm² :-

$\sf{2.94\ m^2=2.94\times10000\ cm^2}\\\\\boxed{\boxed{\sf{\color{lime}{=29400\ cm^2}}}}$

Answer 2

$\huge\sf\pink{Answer}$

☞ TSA = 294 cm²

$\rule{110}1$

$\huge\sf\blue{Given}$

✭ Length of each side of a cube = 0.7 m

$\rule{110}1$

$\huge\sf\gray{To \:Find}$

◈ TSA of a cube(in cm²)

$\rule{110}1$

$\huge\sf\purple{Steps}$

We know for a cube,

$\underline{\boxed{\green{\sf TSA=6a^2}}}$

Substituting the given values,

➳ $\sf TSA = 6 \times (0.7)^2$

➳ $\sf TSA = 6 \times 0.49$

➳ $\sf\red{TSA = 2.94 m^2}$

$\qquad$◕ 1 m = 100 cm

On converting

»» $\sf 2.94 × 100$

»» $\sf\orange{294 cm^2}$
