Total surface area of the pyramid = 
Step-by-step explanation:
To find the surface area of the triangular- based pyramid, we will use the formula:
Surface area = Area of base + Area of the three faces
Area of base of the pyramid = Area of equilateral triangle = 

Area of the slant faces of the pyramid is 

Since there are 3 slant surfaces the total surface area of the pyramid =
#1- irrational
#2- whole
#3- rational
#4- natural and whole
