A square-based prism has a base area of 64 square meters and a total surface area of 272 square meters. What is the height of the prism?

Sorry i made a mistake.

 

The base is 64 m^2, so 272-64 = 208. There are 4 triangles, so 208/4 = 52. The area of the triangle is 52, base 8/2=4, so 52*2/8 = hight 13. We can use the pythogoream thereom to solve. 13^2 = 169. base (8/2)^2 = 16. 169-16 = 156. Thus the hight is the square root of 156? im not sure but this is my best bet.
