A triangle is a 2-dimensional object and so its volume - which requires a 3-dimensional object - is always zero.
An equilateral triangle has 3 equal sides
An equilateral triangle has sides and angles. There are 3 sides in any triangle. Edges are in three dimensional figures.

all triangles have 3 sides although an equilateral triangle has 3 sides of equal length and each corner has the same angel as the other 3

A yield sign has 3 corners and is the shape of a triangle. But specifically it is a equilateral triangle. Edited by: A.M.B.
It creates a Rhombus
There are only 5 known regular Platonic solids and they and their properties are:- 1 Tetrahedron: (pyramid) 4 equilateral triangle faces, 6 edges and 4 vertices 2 Hexahedron (cube) 6 square faces, 12 edges and 8 vertices 3 Octahedron: 8 equilateral triangle faces, 12 edges and 6 vertices 4 Dodecahedron: 12 regular pentagon faces, 30 edges and 20 vertices 5 Icosahedron: 20 equilateral triangle faces, 30 edges and 12 vertices All of them can be inscribed inside a sphere.
what is the volume of a square pyramid with base edges of 20 feet and a height of 10 feet
