Final answer:
The capacity of a half-long, 100 hotel pan is measured by its size and depth, and it is calculated by multiplying the length, width, and depth. This non-standard size of pan requires the exact dimensions to determine its volume, and for a hypothetical 6x20 inches with a 4-inch depth pan, the capacity would be about 8.31 quarts.
Step-by-step explanation:
The capacity of a half-long, 100 hotel pan, also known as a steam table pan, is typically measured by its size and depth. While there is no standard naming for a 100-sized pan, the hotel pan size designation typically refers to the full-size pan (12x20 inches) or its fractions. A half-long pan would presumably be half the length of the full-size in one dimension but potentially retaining the full 12 inches in the other, which is a non-standard size. To determine the exact capacity, you would need the pan's dimensions and depth.
For example, if a half-long pan is 6x20 inches with a 4-inch depth, the volume would be calculated by multiplying length, width, and depth (6 inches x 20 inches x 4 inches), giving us a volume of 480 cubic inches. To convert cubic inches to quarts (since gastronorm pans are often discussed in quarts), you divide by 57.75, which is the number of cubic inches in a quart. The resulting capacity would be approximately 8.31 quarts.
