To find the weight of the bar, you can use the formula:
\[ \text{Weight} = \text{Density} \times \text{Volume} \]
Given the density of the bar is \(25\) pounds per cubic foot and the volume is \(5.2\) cubic feet, you can calculate the weight as follows:
\[ \text{Weight} = 25 , \text{pounds/cubic foot} \times 5.2 , \text{cubic feet} \]
\[ \text{Weight} = 130 , \text{pounds} \]
Therefore, the weight of the bar is \(130\) pounds.
