  • triangular pyramid 2right triangular pyramid 2Right triangular prism (a three-dimensional figure) has a triangle base and the apex alligned above the center of the base.
  • 1 base
  • 6 edges
  • 3 faces
  • 4 vertexs

surface area of a Right Triangular Pyramid formula

\(\large{ A_s = \frac{1}{2} \; \left(h_b\;a\right) + \frac{3}{2} \; \left(a\;h_s\right)  }\)

Where:

\(\large{ A_s }\) = surface area

\(\large{ a }\) = edge

\(\large{ h_b }\) = height base

\(\large{ h_s }\) = height side

Volume of a Right Triangular Pyramid formula

\(\large{ V=\frac{1}{6}\; h_b\;a\;h }\)

\(\large{ V=\frac{1}{3}\; A_b\;h }\)

Where:

\(\large{ V }\) = volume

\(\large{ A_b }\) = base area

\(\large{ a }\) = edge

\(\large{ h }\) = height

\(\large{ h_b }\) = height base
