Sorry, the answer cannot be derived from the given information. There is no way to determine the actual shape of the triangle end of your prism. It is certainly not equilateral, but it could be isosceles with legs measuring (which gives a lateral surface area of about 128 sq cm or a total surface area of roughly 143 sq cm) or a right triangle with a short leg of 3 and hypotenuse (which gives a lateral surface area of about 138 sq cm or a total surface area of roughly 153 sq cm), or some other non-standard shape.

My calculator said it, I believe it, that settles it
