We prove an inequality comparing the sum of areas of faces of a parallelepiped to its volume. Then we prove an inequality on a tetrahedron analogous to Weitzenb\"ock's Inequality on a triangle using the inequality on a parallelepiped and Yetter's Theorem. We also give a short proof of Yetter's Theorem.
