Final answer:
The volume of the loaf pan can be found by multiplying its dimensions. Alternative pans include a 9 x 5-inch loaf pan for a larger loaf and a 7.5 x 3.5-inch loaf pan for a smaller loaf.
Step-by-step explanation:
The volume of a rectangular prism, like a loaf pan, can be found by multiplying its length, width, and height. In this case, the dimensions of the loaf pan are 8 inches by 4 inches. Therefore, the volume of the loaf pan is 8 inches × 4 inches × height.
As for alternative pans, there are various options depending on the desired volume. For a larger loaf, you could use a 9 x 5-inch loaf pan. For a smaller loaf, you could use a 7.5 x 3.5-inch loaf pan.
