Answer 2

$\huge{\mathcal{\blue{\underline{Answer}}}}$

$tsa \: of \: cube = 6(side) {}^{2} = 150cm { }^{2} \\ 6(side) {}^{2} = 150cm {}^{2} \\ (side) {}^{2} = \frac{150cm {}^{2} }{6} \\ (side) {}^{2} = 25 cm {}^{2} \\ side = \sqrt{25cm {}^{2} }$

$\huge{\mathcal{\blue{\underline{Length\:of\:the\:side=5cm}}}}$

The perimeter of any one of its face

$= 4(side) \\ = 4(5cm)$

$\huge{\mathcal{\blue{\underline{20cm}}}}$
