Question

this equation shows density, d, is equal to mass, m, divided by volume, v. to solve as a one - step equation, place the variables you know into the equation. then solve for the unknown variable.
solve

1. a cube of metal measures 3cm on each side. it has a mass of 216g. what is the density of the metal?

Explanation:

Step1: Calculate volume of cube

The volume formula for a cube is $V = s^3$, where $s = 3$ cm. So $V=3^3=27$ $cm^3$.

Step2: Calculate density

Use the density formula $D=\frac{m}{V}$, with $m = 216$ g and $V = 27$ $cm^3$. So $D=\frac{216}{27}=8$ g/$cm^3$.

Answer:

8 g/$cm^3$
