#### Formula:

b = (6 x v) / (5 x h x a)
**Where,**
b = Base Length
v = Volume of the Pyramid
h = Height of the Pyramid
a = Apothem Length of Pyramid
### Example:

A Pentagonal pyramid has a volume of 65 cm^{3}, height of 12 cm and Apothem length as 15 cm. Find Base Edge of the pyramid.

#### Solution

Base Length = (6 x v) / (5 x h x a)

= (6 x 65) / (5 x 12 x 15)

= 390 / 900

= 0.4333 cm
