<p>Answer: 4
If there were 3 faces of the shape, then the shapes would not be able to connect to make something 3D. However, if there are 4 faces of a shape, you can connect all 4 to create a 3D solid, a tetrahedron. Sorry if this explanation is a bit confusing, just look at a picture of a tetrahedron and you should understand: <a href="http://www.coolmath.com/reference/images/polyhedra-tetrahedron.gif%5B/url%5D"&gt;http://www.coolmath.com/reference/images/polyhedra-tetrahedron.gif&lt;/a&gt;&lt;/p>

<p>A tetrahedron actually has 4 faces. The answer is C. the_pakalypse's explanation, however, is still correct if you replace all 2's with 3's and all 3's with 4's.</p>
