Question:

What is the sum of the measures of the angles of a tetrahedron?

Consider the sum of the measures of the face angles of a cube. A cube has six square faces, and since each face has four right angles, the sum of the measures of the angles on each face is 360°; hence, the sum of the measures of the face angles of a cube is 6(360°) 5 2,160°.
