Final answer:
The volume of a standard 9-inch round baking dish is approximately 63.6 cubic inches, or about 13.7 cups. Alternative pans with a similar volume include an 8x8 inch square pan or an 11x7 inch rectangular pan.
Step-by-step explanation:
When looking for the volume of a standard 9-inch baking dish, we assume it is round with a standard depth of about 2 inches. To find the volume, use the formula for the volume of a cylinder: V = πr²h, where r is the radius and h is the height (depth). For a 9-inch diameter, the radius is 4.5 inches. So the volume is π*(4.5 inches)²*2 inches, which calculates to approximately 63.6 cubic inches. In cooking terms, this translates to about 13.7 cups, since one cup is about 14.4 cubic inches.
If you need an alternative pan, you could use an 8x8 inch square pan or an 11x7 inch rectangular pan, both of which have a similar volume and would work for most recipes that call for a 9-inch round pan.
