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
