The Volume of a Triangle Based Pyramid calculator computes the volume (V) of a pyramid with a triangle base that is defined by the length of the three triangle base sides (a,b,c) and height (h) from the base to the apex. 
INSTRUCTIONS: Choose units and enter the following:
- (a) Length of side a of the base of the pyramid.
- (b) Length of side b of the base of the pyramid.
- (c) Length of side c of the base of the pyramid.
- (h) Height of the pyramid. This is the distance between the base and the top.
Pyramid Volume (V): The volume is returned in cubic meters. However, the user can automatically convert this to any of the other volume units (e.g. cubic feet, liters, or gallons) via the pull-down menu.
The Math / Science
The formula for the volume of a pyramid with a triangle base is:
`V = 1/3 * h * sqrt((a+b+c)/2((a+b+c)/2-a)((a+b+c)/2-b)((a+b+c)/2-c))`
where:
- V = volume of pyramid
- h = height of pyramid
- a = side length of base
- b = side length of base
- c = side length of base
