​

Answer 1

Step-by-step explanation:

$\tt{\bold{\blue{\underline{\underline{GIVEN}}}}}$

●Length of the cube =20cm.⠀⠀⠀⠀

$\sf{\bold{\red{\underline{\underline{To\:Find}}}}}$

●Surface area of the cube.

$\sf{\bold{\red{\underline{\underline{Formula}}}}}$⠀⠀⠀⠀

$\sf\boxed{\underline{\underline{\mathcal\color{gold}{6a^2}}}}$

$\sf{\bold{\purple{\underline{\underline{Solution}}}}}$

⏩The surface area (TSA) of a cube is the sum of the areas of its six faces.

⏩surface area of a cube=$6a^2$

 :$\implies{6×(20)^2}$

:$\implies{6×20×20}$

:$\implies{2400~m^2}$

$\sf{\bold{\green{\underline{\underline{Answer}}}}}$

$\pink{\boxed{\boxed{2400~m^2}}}$
