Question

Can the values be added or subtracted? If one value needs to be converted to another, describe the conversion.

19.75 in² + 26.2 in³

A.
The values cannot be added because one is measuring area and the other is measuring volume.

B.
The values can be added without making a conversion of units because they both measure area.

C.
The values can be added after making a conversion of units because they both measure area.

D.
The values cannot be added because one is measuring area and the other is measuring mass.

Answer 1

one of these equations, the one with in^2, measures area, while in^3 measures volume. Does this help?

Answer 2

no

Answer 3

ok, so the first equation is a measure of, for example, how much carpet would cover a room, or area. The second equation is a measure of, for example, how much stuff could fit in a box, or volume. The two cannot be added because they are measuring two different spatial quantities. any better?

Answer 4

no
