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] & [tex]$2 \, lb$[/tex] \\
\hline
X & [tex]$122 \, cm^3$[/tex] & [tex]$3 \, lb$[/tex] \\
\hline
Y & [tex]$56 \, cm^3$[/tex] & [tex]$1 \, lb$[/tex] \\
\hline
Z & [tex]$18 \, cm^3$[/tex] & [tex]$7 \, lb$[/tex] \\

\end{tabular}

Which object has the most mass?

A. W

B. X

C. Y

D. Z



Answer :

To determine which object has the most mass, we need to compare the weights of each object. Let’s look at each row in the table:

1. Object W has a weight of 2 lbs.
2. Object X has a weight of 3 lbs.
3. Object Y has a weight of 1 lb.
4. Object Z has a weight of 7 lbs.

Now, we compare these weights to find the object with the maximum weight:

- Compare 2 lbs (Object W) with 3 lbs (Object X): Object X has more mass.
- Compare 3 lbs (Object X) with 1 lb (Object Y): Object X still has more mass.
- Compare 3 lbs (Object X) with 7 lbs (Object Z): Object Z has more mass.

Therefore, among the objects W, X, Y, and Z, Object Z has the most mass, with a weight of 7 lbs.

The solution to the question is:
Object Z.
