Question

find the total surface area of a cube whose edge measures 22 metre​

Answer 1

$\purple{ \sf \underline{\huge{ \fbox{ \: \pink{Solution : \: \: \: }}}}}$

Given ,

Side of cube = 22 m

We know that , the total surface area of cube is given by

$\large \mathtt{ \fbox{TSA \: of \: cube = 6 {(side)}^{2} }}$

Substitute the value , we obtain

$\sf \hookrightarrow TSA = 6 \times {(22)}^{2} \\ \\ \sf \hookrightarrow TSA = 6 \times 484 \\ \\ \sf \hookrightarrow TSA = 2904 \: \: {m}^{2}$

Hence , the total surface area of cube is 2904 m²
