Question

abi measures the volume and weight of four objects and records his data in this table.
volume and weight

object	volume	weight
x	122 cm³	3 lb
y	56 cm³	1 lb
z	18 cm³	7 lb

which object has the most mass?
○ w
○ x
○ y
○ z

Explanation:

Step1: Recall the relationship between weight and mass

In the context of this problem (assuming the same gravitational field, which is a common approximation), weight is proportional to mass. So, the object with the greatest weight will have the greatest mass.

Step2: Compare the weights of the objects

• Object W: 2 lb
• Object X: 3 lb
• Object Y: 1 lb
• Object Z: 7 lb

Among these weights (2 lb, 3 lb, 1 lb, 7 lb), 7 lb is the largest, which corresponds to Object Z.

Answer:

Z (Object Z has a weight of 7 lb, which is the greatest among the four objects, and since weight is proportional to mass in the same gravitational field, Object Z has the most mass.)
