Ohm's law (V = I*R) applies at constant temperature. To find the resistance of a material at a given temperature "T", use the values at a reference temperature (here 20 degrees) and apply the formula: Res = R20*(1+Alpha20*(T-20)). Round your final answer "Res" to three digits.
Hint: Use the right brackets to reference table values.
