Answer:
The green square: 252 because 28 x 3 = 84 and 84 x 3 = 252
Explanation:
Since the baker is making 28 cakes each day for 3 days, that means that the total number of cakes the baker makes is 28 x 3.
Now that we know the baker made 84 cakes we also know that for each cake he uses 3 cups of flour. This means that to get the number of cups of flour we used we need to count 3 cups for ever cake he made, so 84 x 3.
Thus giving us the final result of 252 cups of flour.
