Amy has 2 rows of 4 sports trophies each on 1 shelf.
To find out how many trophies are on each shelf, we have to multiply 2 * 4. When you do this, you get 8.
Thus, to find out how many trophies Amy has, we have to multiply the number of trophies on each shelf (8) by the number of shelves (3).
8 * 3 = 24
Therefore, Amy has 24 trophies.
Hope this helps! :)
