To find the volume of the stack of pennies on the right, we first need to recognize that the volume of the stack of pennies on the left, which is shaped like a right cylinder, is provided as 360 mm³. Since both stacks consist of the same number of pennies (15 pennies each), we can assume that the volume of the stack on the right is equal to that of the stack on the left, provided that no additional information about the shape or arrangement of the pennies on the right is given.
Therefore, the volume of the stack of pennies on the right is also:
360 mm³
So the answer you should enter in the blank is:
360
