the solid object has a density of 3 grams per cubic centimeter. what is the mass of this object? 0.5 g 2 g…

Explanation:

Step1: Calculate volume of object

The object is a rectangular - prism. The volume formula for a rectangular - prism is $V = l\times w\times h$. Here, $l = 3$ cm, $w = 2$ cm, and $h = 1$ cm. So $V=3\times2\times1 = 6$ $cm^{3}$.

Step2: Calculate mass using density formula

The density formula is $\rho=\frac{m}{V}$, where $\rho$ is density, $m$ is mass, and $V$ is volume. We know $\rho = 3$ g/$cm^{3}$ and $V = 6$ $cm^{3}$. Rearranging the formula for $m$ gives $m=\rho\times V$. Substituting the values, we get $m = 3\times6=18$ g.

Answer:

18 g
