A minimum of 2 triangles are needed, but you can also make a rectangle with 3 or more triangles.

A triangular pyramid. It has triangles on its 3 sides and a triangle on the bottom for a base.

A triangular prism.
The simplest pattern is 2n+1, so the 16th figure will have 33 triangles. Of course, if you are creating new triangles and also keeping the old triangles, this would be different.

If the triangles are congruent then it is a triangular-based prism.

A rectangle is a 2-dimensional figure. 2-d figures do not have volumes, which is a 3-dimensional concept.

A triangulare prism
It depends on the rectangle, but in any case, a rectangle is a 2-dimensional figure so it cannot have measurements in 3 dimensions!
