Answer:
I have 126 ounces of cereal.
Step-by-step explanation:
A box of cereal has a net weight of 42 ounces. If i buy three of these boxes then I have to tell the total weight of cereal i have.
Since weight of 1 box of cereal = 42 ounces
So weight of 3 boxes of cereal = 42 + 42 + 42 = 3 × 42
Total weight = 126 ounces
Therefore, I have 126 ounces of cereal.
