### Problem Statement

Find the average temperature in the box \( D = \{(x, y, z): 0 \leq x \leq \ln 3, \, 0 \leq y \leq \ln 9, \, 0 \leq z \leq \ln 27\} \) with a temperature distribution of \( T(x, y, z) = 15 \, e^{-x-y-z} \).

### Solution

**The average temperature is** \(\underline{\phantom{a}}\).

*(Type an exact answer.)*

---

In this exercise, you are asked to find the average temperature within a defined 3D space, where the temperature distribution is provided as an exponential function. The box \( D \) is defined by logarithmic bounds in each spatial dimension.
