Answer : 54 pieces
Step-by-step explanation:
Notice that the 2.5 in size of the small square pieces can fit 9 times in the length of the cake:
so 9 pieces can fit in a row along the long side (length) of the cake.
at the same time, this small square portion can fit 6 times in the cake's width:
Therefore, you can fill a matrix of 6 columns and 9 rows with these little square pieces, which gives you a total of : 9 times 6 square portions. That is a total of 54 square portions of side 2.5 inches.
