Final answer:
The maximum number of half-height blades that can be installed in the chassis when 6 full-height blades are already installed is 8.
Step-by-step explanation:
The blade chassis can hold 16 half-height blades or 8 full-height blades. The question asks for the maximum number of half-height blades that can be installed in the chassis when 6 full-height blades are already installed. Since a full-height blade occupies twice the space of a half-height blade, we can calculate the remaining space in terms of half-height blades. There are 8 full-height blades already taking up 16 half-height spaces, which leaves us with 8 half-height spaces. Therefore, the maximum number of additional half-height blades that can be installed in the chassis is 8.
