# 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 cm3

volume of cube = (side)3 = 8

side = 2 cm

Length between the parallel faces = 2 cm

Area of cross section = 2 x 2 = 4 cm2

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
