Code to add this calci to your website  #### 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 cm3, 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
