Resistance of metallic wire, R = 26 ohms,
Length of wire, l = 1 m 
Area of cross section = 2 cm2 = 0.0002 m2  
Resistivity, ρ =? 
 
Resistivity is given as,
 
rho space equals space fraction numerator R A over denominator l end fraction
ρ = (26× 0.0002)/ 1 = 0.0052 = 5.2 × 10-3  Ωm 
 
Thus  resistivity of the metal is 5.2 ×10-3 Ωm
