Final answer:
The 10 x 15 x 1-inch jellyroll pan has a volume of 150 in.³. Substitute pans should have a similar volume, such as two 8 x 8 x 2-inch pans with a volume of 128 in.³ each, though adjustments in baking time and fill level may be necessary.
Step-by-step explanation:
The recipe calls for a 10 x 15 x 1-inch jellyroll pan. To find the volume of this pan, you can use the formula for the volume of a rectangular prism, which is:
Volume = length × width × height
So, the volume of the pan is:
Volume = 10 in. × 15 in. × 1 in. = 150 in.³.
If you need to find a substitute for this specific pan, look for another baking pan that has a similar volume. For instance, if you have two 8 x 8 x 2-inch square pans, each pan would have a volume of:
Volume = 8 in. × 8 in. × 2 in. = 128 in.³ per pan.
Using two of these pans would give you a total volume of 256 in.³, which is more than the required 150 in.³, but it can still work if you adjust the baking time and make sure not to overfill the pans.
