ANSWER:
147.868 mL of water is required to make an ice cube.
SOLUTION:
Given that, an ice cube is made up of 5 fluid ounces of water.
We need to find how many milli liters of water does it require to make an ice cube.
For, that we have to convert 5 fluid ounces in to units of milli liters.
We know that, 1 US fluid ounce equals to 29.5735 milli liters. i.e. 1 US fluid ounce = 29.5735 mL
Now,
An ice cube is made by 5 fluid ounces = 5 x 1 fluid ounce
= 5 x 29.5735 mL = 147.868 mL
Hence, 147.868 mL of water is required to make an ice cube.
