Final answer:
To determine if the volume of 9 tubes of toothpaste is greater than 1 cup, convert the volume from fluid ounces to cups and compare the two quantities.
Step-by-step explanation:
To determine if the volume of 9 tubes of toothpaste is greater than 1 cup, we need to compare the two quantities.
First, convert the volume of 9 tubes of toothpaste from fluid ounces to cups. There are 8 fluid ounces in 1 cup, so 9 tubes of toothpaste would be 9 x 2 = 18 fluid ounces. Dividing 18 fluid ounces by 8, we get 18/8 = 2.25 cups.
Since 2.25 cups is greater than 1 cup, the volume of 9 tubes of toothpaste is indeed greater than 1 cup.
