Question

By mistake, a quart of oil was dumped into a swimming pool that measures 25.0 m by 30.0 m. The density of the oil was 0.750 g/cm3. Assuming the oil spread into a uniform, thin layer over the water, how thick was the oil slick?

Answer 1

The oil slick thick = 1.257 x 10⁻⁶ m

Further explanation

Volume is a derivative quantity derived from the length of the principal

The unit of volume can be expressed in liters or milliliters or cubic meters

The volume of the aquarium is almost the same as the beam namely:

V = length x width x height

1.06 quart = 1 L

1 quart = 0.943 L=0.943 x 10⁺³ m³

volume of oil = volume of swimming pool

0.943 x 10⁺³ m³ = 25 x 30 x h

$\tt h=\dfrac{V}{A}\\\\h=\dfrac{0.943\times 10^{-3}~m^3}{25\times 30~m^2}\\\\h=1.257\times 10^{-6}~m$
