Question 155041: Please help me find the volume, to the nearest tenth, of a pyramid that is 6 feet tall and whose base is an equilateral triangle with sides each 10 feet long? Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! The volume of a regular pyramid is found by: where: B = area of the base and h = the height of the pyramid.
In this problem, using Heron's formuls for the area of a triangle when the three sides are known. S = Semi-perimeter = 30/2 = 15,
a = b = c = 10, so...
So the volume of the pyramid is: Cubic feet.
