Alright assuming they mean total surface area since they didn't say lateral the equation to follow would be S= Ph + 2B

Start with P:
P stands for perimeter, so add up all the edges on one face of the cube.



17 + 17 + 17 + 17 = 68
Then your equation becomes
S= 68×h + 2B
h=height and that's obviously 17
so, S= 68×17 +2B

Now to find B. This is pretty easy. All you need to do is take 17×17 because you're finding the area of the base. This equals 289.

Finally this leaves us with the equation
S= 68×17+2×289

From there on you just solve it out.
This would leave you with 1734.
