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

**Volume and Weight**

\begin{tabular}{|c|c|c|}
\hline
Object & Volume & Weight \\
\hline
W & [tex]$10 \, cm^3$[/tex] & 2 lb \\
\hline
X & [tex]$122 \, cm^3$[/tex] & 3 lb \\
\hline
Y & [tex]$56 \, cm^3$[/tex] & 1 lb \\
\hline
Z & [tex]$18 \, cm^3$[/tex] & 7 lb \\
\hline
\end{tabular}

Which object has the most mass?

A. W
B. X
C. Y
D. Z

Answer :

To solve the problem of determining which object has the most mass from the given data, follow these steps:

1. Understand the problem: We need to determine which object (W, X, Y, or Z) has the most mass. The mass can be inferred directly from the 'Weight' column in the table since weight reflects the gravitational force on the object due to its mass.

2. Analyze the given data: We are provided with the volume and weight of each object as follows:
- Object W: Volume = 10 cm³, Weight = 2 lb
- Object X: Volume = 122 cm³, Weight = 3 lb
- Object Y: Volume = 56 cm³, Weight = 1 lb
- Object Z: Volume = 18 cm³, Weight = 7 lb

3. Identify weight values: Extract the weight values from the table:
- Weight of W: 2 lb
- Weight of X: 3 lb
- Weight of Y: 1 lb
- Weight of Z: 7 lb

4. Compare the weights: Determine which object has the greatest weight:
- W: 2 lb
- X: 3 lb
- Y: 1 lb
- Z: 7 lb

From the comparison, it is clear that Object Z has the highest weight at 7 lbs.

Therefore, the object with the most mass is Z.
