The depth of the pan is not as important (most pans are between 1 and 4 inches deep), but it is the length and width that are more important in determining how many people a cake can feed.
You can use two cake recipes for that size pan.
You should get six 4x4 servings with a a 1x9 on the bottom ans a 1x13 on the side left over. So, basically 7 servings.
A standard 13 x 9-inch pan typically yields about 12 to 15 servings, depending on how you cut the portions. For desserts like brownies or cakes, cutting them into smaller squares can increase the number of servings. Conversely, if you're serving a main dish like lasagna, you might opt for larger portions, resulting in fewer servings. Ultimately, the serving size will depend on the type of dish and the appetite of your guests.

The number of servings in 16 cups depends on the serving size. For example, if a serving is 1 cup, then 16 cups would equal 16 servings. If the serving size is ½ cup, there would be 32 servings. Thus, the total servings can vary based on the designated serving size.

The order you get at Dominos is about an 8×8 pan size, and is supposed to be 9 servings, or you could eat it all by yourself if you believe in yourself.
The number of servings from 108 cups of punch depends on the serving size. If each serving is typically 1 cup, then you can make 108 servings. However, if the servings are smaller, for example, ½ cup each, you would have 216 servings. Adjust the total based on the desired serving size.
9 inches x 9 inches = 81 one inch servings
The number of servings in 5 quarts depends on the serving size. For example, if a serving size is 1 cup (which is 0.25 quarts), then 5 quarts would provide 20 servings. If the serving size is different, such as ½ cup (0.125 quarts), then it would yield 40 servings. To determine the exact number of servings, divide 5 quarts by the serving size in quarts.
