Answer 1

41 is not right.
44 is not right.
45 is correct. A cm is 1/100 of a meter.
Hint: If I multiply 2 ft x 3 ft I get 6 square feet, a unit of area.
If I multiply 2 ft wide by 3 ft long by 3 ft high, I get 18 ft^3 which is the volume of that object.
Second hint: density = m/v so what unit is m and what units are v; therefore what is m/v.

Answer 2

What about 42 and 43?
