Final answer:
Push buttons in a garage must typically be installed at a minimum height of 5 feet above the garage floor to prevent accidental operation by small children, according to common safety and building standards in engineering.
Step-by-step explanation:
The question refers to the standard installation height for push buttons in a garage setting, which would fall under building codes and regulations, a topic that is in the realm of Engineering. Specifically, these dimensions are likely detailed in electrical codes or building standards that outline the optimal height for such installations for safety and accessibility reasons. While the exact height requirement can vary by local codes, a common standard is to place push buttons used to open garage doors no less than 5 feet (60 inches) above the garage floor. This height consideration is to prevent small children from accidentally operating garage doors.
