Kelly and Adam are buying candy boxes to give to friends
Step-by-step explanation:
Kelly statement is true.
1. Kelly buy a candy box which is cone -shaped with radius x.
2.Adam buy a candy box which is square pyramid shape with same height as Kelly's box but the side length is xπ√.
3.Two candy boxes have different in shape so volumes of the boxes will be different.
We assume that you don't want to count numbers that start with 0, so there are 4 possible first digits and 5 possible digits in each of the remaining places.
4*5^3 = 500 . . . . total number of 4-digit numbers using only even digits
