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.

Okie, the terms are similar in that they both have inches, but they are in different forms. The first has inches to the 2nd power. This is a unit for area. The second has the units of inches to the 3rd power. This is a unit of volume. To convert from area to volume, you would need a conversion but it usually would be from a problem with certain values. Ex. Think of a cube, the 2 sides multiplied would be area and third multiplied in would be volume. If you are adding an area to a volume, you would need to know of which since you cannot change volume magically to area or area magically to volume if you do not know the details of the problem. The answer is A; I hope this helps :-)

Its d so thats how it would would back from 1.0 form three four two
