Answer
For the first row, when numOne = 5, numTwo = 6, and numThree = -1, the calculations to derive the final output would be:
Since one of the numbers is negative, we cannot compute volume accurately. Thus, the output reads as: Area 30.
Step 2
Complete the trace table for numOne = 10, numTwo = 4, numThree = 0

Answer
For the second row, with numOne = 10, numTwo = 4, and numThree = 0, the program will likely output: Volume 0 since numThree is zero.
Step 3
Complete the trace table for numOne = 3, numTwo = 5, numThree = 10

Answer
In the third row, when numOne = 3, numTwo = 5, and numThree = 10, the output will be: Volume 150, calculated based on the provided inputs.

Answer
One way to enhance the robustness of the program is to implement input validation. For instance, checking whether the height (e.g., numThree) is a positive number before calculations are performed would prevent runtime errors and incorrect outputs.
