Final Answer:

The volume of the cube is
\(b^3\), and the height of each square pyramid formed by the four diagonals of the cube is
\(h = (b)/(2)\).

Step-by-step explanation:

The volume of a cube with side length
\(b\) is given by
\(V = b^3\). In the context of the problem, drawing the four diagonals of the cube creates six square pyramids with the same base as the cube. Each pyramid shares a common vertex with the center of the cube.

The height
(\(h\)) of these pyramids is equal to half the side length of the cube, i.e.,
\(h = (b)/(2)\).

The formula for the volume
(\(V_p\)) of a square pyramid with base
\(b\) and height
\(h\) is \(V_p = (1)/(3)b^2h\). Substituting
\(h = (b)/(2)\) into this formula, we get
\(V_p = (1)/(3)b^2 \cdot (b)/(2) = (1)/(6)b^3\).

Since there are six identical square pyramids formed by the cube's diagonals, the total volume of the six pyramids is
\(6 \cdot (1)/(6)b^3 = b^3\). Hence, the final answer is that the volume of the cube is
\(b^3\), and the height of each pyramid is
\(h = (b)/(2)\).
