Question

The espression 6x2 gives the surface area of cube find the surface area if ×=2m

Answer 1

the espression 6x2 gives the surface area of cube find the surface area if ×=2m ​

we have that

surface area of cube is

`SA=6x^2`

If x=2 m

substitute

`\begin{gathered} SA=6(2)^2 \\ SA=6\cdot4 \\ SA=24\text{ m\textasciicircum{}2} \end{gathered}`

the surface area is 24 square meters
