Given the mass of the aluminium is
Density of the aluminium is
The specidic resistance of the aluminium is
Now the volume of the block is
a) Given the diameter is equal to its height
We know the formula for the volume of the cylinder in terms of diameter is
From this
We know the formula for the resistance is
b)In this case we have to calculate the resistance between theopposite faces of the aluminium cube.
We know the formula for the cube is
From this the length of the cube is
Now the resistance between the opposite faces of the cubeis
