QUESTION:

Partitioning a cube Consider the region \(D_{1}=\{(x, y, z): 0 \leq x \leq y \leq z \leq 1\}\).

a. Find the volume of \(D_{1}\).

b. Let \(D_{2}, \ldots, D_{6}\) be the “cousins” of D1 formed by rearranging x, y, and z in the inequality \(0 \leq x \leq y \leq z \leq 1\). Show that the volumes of \(D_{1}, \ldots, D_{6}\) are equal.

c. Show that the union of \(D_{1}, \ldots, D_{6}\) is a unit cube.
