Question

(a) A rectangular gasoline tank can hold 38. 0 kg of gasoline when full. What is the depth of the tank if it is 0. 400 m wide by 0. 900 m long? FYI, the table of densities in the textbook refers to gasoline as "petrol"

Answer 1

ρ = .68 g / cm^3 = 680 kg / m^3 for gasoline

M = ρ V = 38 kg

V = 38 kg / 680 kg/m^3 = .056 m^3

.4 * .6 * D = .056 m^3

D = .23 m
