**Problem Translation:**
All edges of the triangular pyramid \(ABCD\) are of length \(3\) cm. Points \(P\) and \(Q\) lie on the edges \(AC\) and \(BC\), respectively, with the segments \(CP\) and \(CQ\) each measuring \(1\) cm. Find the volume of the pyramid \(ABPQD\).

---

### Solution Outline:

To solve this problem, we need to use the concept of similar triangles or tetrahedrons and apply the volume formula for a pyramid, which is:
\[
V = \frac{1}{3} \times \text{Base Area} \times \text{Height}
\]

Since \(ABCD\) is an equilateral triangular pyramid (a regular tetrahedron) with side lengths of \(3\) cm, we can find its volume first and then use proportional reasoning to determine the volume of \(ABPQD\).

Would you like a step-by-step solution of this approach, or do you have any questions?

### Further Exploration Questions

1. How do we calculate the volume of a regular tetrahedron based on its side length?
2. What is the method to find the centroid or height of a tetrahedron given its vertices?
3. How can we use similar figures to find volumes when certain segments are proportionate?
4. What mathematical properties define a regular tetrahedron?
5. How would the solution change if only two edges of the tetrahedron were equal?

### Tip
For pyramids and other polyhedra, breaking down complex shapes into smaller, more manageable shapes (like triangles or simpler pyramids) can simplify volume calculations.

Всички ръбове на триъгълната пирамида ABCD са с дължина 3 см. Точките P и Q лежат съответно на ръбовете AC и BC, като дължините на отсечките CP и CQ са равни на 1 см. Да се намери обемът на пирамидата ABPQD.
