An environmental sensor records an atmospheric pressure index represented as a single-byte hexadecimal value, C5C5C5.
Convert this hexadecimal value to an 8-bit binary integer, and then convert this binary representation into a denary (base-10) integer to find the actual sensor reading. Show your working.
