a solid cube of silver has a mass of 84.0 g .what is the resistance between opposite face .density of silver is 10.50 g/cm 3and its resistivity at 20 degree celcius . is 1.47 multiply 10 -7 (10 to the power -7) ohm meter

We know that

In the given question, they gave mass and density from which we can calculate the volume of cube.

Volume = Mass / density = 84 / 10.5 = 8 cm^{3}

volume of cube = (side)^{3} = 8

side = 2 cm

Length between the parallel faces = 2 cm

Area of cross section = 2 x 2 = 4 cm^{2}

Resistivity = 1.47 x 10^{-7} ohm meter = 1.47 x 10^{-5} ohm cm

R = 1.47 x 10^{-5} x 2 / 4 = 0.735 x 10^{-5}

**R = 7.35 x 10 ^{-6} ohm or 7.35 micro ohm**
