Answer
a) $2.54 \times 10^{-3}\; m^{3} $
b) $1.95 \times 10^{-4}\; m$
Work Step by Step
a)
0.67 US gallons
= $0.67\; US\; gallons \times \frac{3.785 \times 10^{-3}\; m^{3}}{1\; US\; gallon} $
$\approx 2.54 \times 10^{-3}\; m^{3} $
b)
$\frac{2.54 \times 10^{-3}\; m^{3} }{13\; m^{2}}$
$\approx 1.95 \times 10^{-4}\; m$
