01. John converted
his mass from kilogram to gram and got an answer of 0.072 grams. How do you know that the answer is unreasonable?
02. Alice calculated the volume of a box heat and got an answer of 2.56 centimeter. Can this be correct ? How do you know?

1. You won't. 0.072 gram expressed in kilogram is 0.000072 kilograms. Except for the fact, it is unreasonable to express such a small mass using kilograms, the conversion itself is perfectly acceptable.
2) centimeter is a unit of length. To express volume, the unit has to be in terms of cube of the length, or use such unit as cc, liter, etc. Simply a wrong unit to use.

1. 0.072 grams is less than a pencil weighs. Unless John is a common housefly, then it's unreasonable. If he is a housefly, then he has no business trying to calculate his mass anyway. Why do flies always gotta act like they're so cool?
2. Any answer for volume needs to be in cubic dimensions. In this case, it should be in cubic centimeters (cm3), not centimeters. Alice goofed.

Well, if he converted that to grams, it would have initially been 0.000072kg, which is an utterly absurd weight. I don't know why it's unreasonable, unless it's referring to his own weight, because it's roughly the weight of a hair.
number 2, god, I hate maths. volume is measured in cubes, and her measurement is centrimeters, which is length, so it probably isn't correct, unless it's centimeters cubed.

1.He divided his KG mass by 1000 as opposed to multiplying it by 1000. Simple metric stuff.
2. It is incorrect volume whether it be in CMs, Meters or otherwise (non liquid) should be cubed so her answer should be 2.56cm^3 or you could come up with 2.56 centiliters (yes it does exist)
