5. How many free electrons are there in a rectangular block of a conductor whose dimension is 8 m by 4 m by 3 m? The electrons of this conductor have a drift velocity of 4 m/s when a 9.6 A of current is applied thru a cross-sectional area of 0.005 m2. Use electronic charge of 1.6 x 10-19 coulomb per electron. Express your answer in scientific notation whose unit is electrons per cubic meter.
