That is called a pyramid.
a triangle has 1 face but if you mean a pyramid (3-D triangle) it has4 but a (a 3-D triangle with a square bottom) it has 5.
There is no such thing as a triangular box or cube. A 3-D triangle is called a pyramid.
A triangle has 3 angles and 3 sides, which is why it is called a TRIangle.
It looks like a 3-D triangle.
