Question

The volume of a cube is found by cubing the length of one of its edges. So, the volume in cubic centimeters is $13^3 = 2197 \, \text{cm}^3$. To convert cubic centimeters to cubic meters, we use the conversion $1 \, \text{m}^3 = 10^6 \, \text{cm}^3$, so $2197 \, \text{cm}^3 = 2.197 \times 10^3 \, \text{cm}^3 = 2.2 \times 10^{-3} \, \text{m}^3$, since $2.197$ rounds to $2.2$ when expressed with two significant figures.
