Question

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.

Answer 1

61.8

Explanation:

Answer 2

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
