Mass = 84g

Density =10.50 g/cm^3

Volume = 8 cm^3 by mass /density

Volume =l^3

8cm^3 =l^3

L^3 = 8cm

L=2cm

Area = l^2 as we have to calculate resistivity between two opposite faces .

Area = 0.02m×0.02m

R= 1.47 ×10^-7×0.02/0.02×0.02

R=73.5 ×10^-7

R=0.735 ×10^-5

Given:

mass = 84g

density = 10.50g/cm³

Resistivity = 20°C

To Find:

Resistance between the opposite phases

Explanation:

Volume = 8 cm³ by mass /density

Volume =l³

8cm³ =l³

L³= 8cm

L=2cm

Area = l² as we have to calculate resistivity between two opposite faces .Area = 0.02m×0.02m

R= 1.47 ×10⁻⁷×0.02/0.02×0.02

R=73.5 ×10⁻⁷

R=0.735 ×10⁻⁵

Answer = 0.735×10⁻⁵
