Final Answer:

The density of the block of metal is approximately 318.18 grams per cubic meter.

Step-by-step explanation:

Density is defined as the mass of an object per unit volume. To calculate density, we use the formula:


\[Density (ρ) = (Mass (m))/(Volume (V))\]

Given that the volume of the metal block is
\(13.2 \, \text{in}^3\) and the weight is \(5.22 \, \text{pounds}\), we first need to convert these units to a consistent system. Converting the volume from cubic inches to cubic meters, we use the conversion factor
\(1 \, \text{in}^3 = 0.000016387 \, \text{m}^3\):


\[Volume (V) = 13.2 \, \text{in}^3 * 0.000016387 \, \text{m}^3/\text{in}^3\]

Next, we convert the weight from pounds to grams, using the conversion factor
\(1 \, \text{pound} = 453.592 \, \text{grams}\):


\[Mass (m) = 5.22 \, \text{pounds} * 453.592 \, \text{grams/pound}\]

Now, we substitute these values into the density formula:


\[Density (ρ) = \frac{5.22 \, \text{pounds} * 453.592 \, \text{grams/pound}}{13.2 \, \text{in}^3 * 0.000016387 \, \text{m}^3/\text{in}^3}\]

After performing the calculations, the density is approximately
\(318.18 \, \text{grams/m}^3\). Thus, the density of the metal block is approximately
\(318.18 \, \text{grams per cubic meter}\), indicating the mass of 318.18 grams occupies each cubic meter of space.
