There are 24 ounces in 3 cups.
This is a conversion within the US customary system of volume. The relationship between cups and fluid ounces is a fixed standard that must be known.
A) 5
Five ounces is less than the amount in a single cup (8 ounces). For three cups, the total must be greater than 8. This value is implausibly low and suggests a major misunderstanding of the units or the operation required (perhaps division instead of multiplication).
B) 8
The number 8 is the conversion factor: 1 cup = 8 fluid ounces. This option presents the factor itself as the answer, not the result of applying that factor to the quantity of 3 cups. It answers the question "How many ounces are in 1 cup?" instead of "How many ounces are in 3 cups?"
C) 11
There is no standard relationship or simple arithmetic that yields 11 ounces from 3 cups. It does not equal 3 multiplied by 8, nor does it correspond to any other common volume conversion in this system. It is an incorrect calculation.
D) 24
This is the correct calculation. Using the standard equivalence 1 cup = 8 US fluid ounces, the conversion is a direct multiplication: 3 cups * 8 ounces/cup = 24 ounces. This is a fundamental conversion used in cooking, baking, and various other practical applications.
Conclusion:
To convert a volume in cups to fluid ounces, one multiplies the number of cups by 8. For 3 cups, this straightforward calculation results in 24 fluid ounces.
