3 is the answer.
Step-by-step explanation:
To calculate the total amount of Enfamil required, we need to multiply the hourly intake by the number of hours:
Hourly intake = 48 mL
Duration of feed = 10 hours
Total volume required = Hourly intake x Duration of feed
Total volume required = 48 mL/hour x 10 hours
Total volume required = 480 mL
Each can of Enfamil contains 235 mL, so we need to determine how many cans will be needed to provide a total of 480 mL:
Number of cans required = Total volume required / Volume per can
Number of cans required = 480 mL / 235 mL per can
Rounding up to the nearest whole number, we get:
Number of cans required = 3
Therefore, we will need 3 cans of Enfamil to provide a 1/4 strength feed of 48 mL per hour for 10 hours.
