Find the surface area of regular prism with height 6 cm, if the base of the prism is: Equilateral triangle with the side 3 cm and altitude of the triangle of approximately 2.6 cm.

Triangular Prism Area = 2*Triangle area + height * (side1+side2+side3)

Triangle Area =.5 * base * altitude

Triangle Area =.5*3*2.6

Triangle Area = 3.9

2 * Triangle Area = 7.8

height * (side1*side2*side3) = 6 * (3+3+3) =

54

Total Area = 7.8 + 54 = 61.8 square centimeters
