An object with a higher mass will have a smaller density.
True or False???

Since density is equal to mass divided by volume, we can determine the relationship between mass, density, and volume. Therefore, we can automatically know that the answer must either be A or B, since this information is determinable. The prompt lists the object as small. Therefore, we know that density is high, but volume is low. Let's examine the equation (D = M/V), where d = density, m = mass, and v = volume. In order for any number to be divided by a smaller number and have the end result be a higher number, the numerator (i.e. mass) must be bigger than the denominator (i.e. volume). We can also see that this is true by substituting in somewhat random numbers for d, m, and v. D = M / V 5 = 10 / 2 10 > 2 M > V In conclusion, your answer is D.
