Answer:
side ratio = 6 : 19.8
Py = Triangular base = 19.8 + 3/2 x 4.4 x 4.4 = 49
Making side 19.8 pyramid y
16 : 49 = SA ratio 6.2 : 19.8 = side ratio
Step-by-step explanation:
With triangular bases we divide by 3/2 to find the surface area.
So that x = 3.1
x original value = 2.4
2.4 (15/6.2) = 3.1
x 6.25 / 2.6 = 2.4
