If you were to measure the volume of an ice cube in your freezer, what would be a reasonable unit to use?
a) cubic feet
b) cubic miles
c) square feet
d) cubic inches

D) cubic inches is the right answer.

Step-by-step explanation:

Ice cubes are small cubes generally a few centimeter to inches. They are not long than an inch.

So, If I was to measure the volume of an ice cube in my freezer, the most reasonable unit to I would use will be cubic inches.

As we have to find the volume, we should cancel out option C as square feet is a unit of area.

Cubic feet and cubic miles are very large units while compared to a small ice cube.

Therefore, the correct answer is option D.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
