Question 551333
For a pyramid, the volume is:
{{{V = B*h}}} where: B = area of the base and h = the height of the pyramid.
Use Hero's formula to find the area of the triangular base:
{{{A = sqrt(S(S-a)(S-b)(S-c))}}} where S = semi perimeter of the triangle and a, b, and c are the lengths of the sides of the triangle.
{{{A = sqrt(15(15-10)(15-10)(15-10))}}}
{{{A = sqrt(15(125))}}}
{{{A = sqrt(1875)}}}
{{{A = 43.3}}}
{{{V = 43.3(6)}}}
{{{V = 259.8}}}cu.ft.
