Question

If one side of an equilateral triangle has length of 6, what is the length of its altitude

Answer 1

Triangular Prism Area = 2*Triangle area + height * (side1+side2+side3)Triangle Area = .5 * base * altitudeTriangle Area = .5*3*2.6Triangle Area = 3.92 * Triangle Area = 7.8
height * (side1*side2*side3) = 6*(3+3+3) =54Total Area = 7.8 + 54 = 61.8 square centimeters
