    b) false

    Explanation:

    false, missing two variables, the current and the material.

    To find the volume of the tube we must know the transverse area and the length.

    It is possible to calculate the length of the tube knowing the resistance, since this is a value that depends on the material, the area and the length.

    It is possible to calculate the electrical resistance using the ohm equation.

    Resitence = Voltage / current.
