The following question comes from the subject test:
A tetrahedron was cut from the corner of a cube, with three of its vertices at the midpoints of three edges of the cube. If tetrahedrons of the same size are cut from the remaining seven corners of the cube, how many faces will the resulting solid have?
Thank you and big hugs!
