\large\sf\underline{Given:}

  • Edges / sides = 3.2 m

\large\sf\underline{To\:find:}

  • Surface area of the cube

\large\sf\underline{Solution:}

We know ,

\large{\mathfrak\purple{Surface\:area\:of\:cube\:=\:6a^{2}}}

  • Let's substitute the value in the formula

\sf:\implies\:Surface\:area\:=6 \times (3.2)^{2}

\sf:\implies\:Surface\:area\:=6 \times 3.2 \times 3.2

\sf:\implies\:Surface\:area\:=6 \times \frac{32}{10} \times \frac{32}{10}

\sf:\implies\:Surface\:area\:= \frac{192}{10} \times \frac{32}{10}

\sf:\implies\:Surface\:area\:= \frac{6144}{100}

{\sf{{\red{:\implies\:Surface\:area\:=\:61.44\:m}}}}

══════════════════╕

\small\rm\purple\star\:\underline{Some\:more\: Formula\:for\:cube:}

⠀‎Surface area = \sf\:6a^{2}

⠀‎Volume = \sf\:a^{3}

⠀‎Diagonal = \sf\:\sqrt{3}a
