To solve the problem step by step, we will calculate the number of conduction electrons in a pure semiconductor given its dimensions and the number density of conduction electrons. ### Step 1: Convert dimensions to SI units The dimensions of the semiconductor are given as: - Length = 1 cm = \(1 \times 10^{-2}\) m - Width = 1 cm = \(1 \times 10^{-2}\) m - Height = 2 mm = \(2 \times 10^{-3}\) m ...
