Center of mass will be at the Centroid of the equilateral triangle.
Length of perpendicular = √[a²-(a/2)²] = (a√3)/2
The centroid divides the perpendicular into 2:1
distance of center of mass from vertex = (2/3)×(a√3)/2 =a/√3
                                                              = 30/√3 = 10√3 cm
