Well, aluminum is Aluminum: 2.7E-8 ohm meters, so I'm gonna go with yes. Thanks!
Resistance is given by R = ρL/A using resistivity, length and cross-section area

R = V/I from Ohms law

Combining you have ρL/A = V/I

so ρ = VA/LI

since you were given the values of V, A, L and I it should just have been a matter of plugging in the values and see what you get.

Note that the actual Resistance value does not ever have to be calculated.
