a company needs to build a rectangular titanium time capsule (box-shaped). it will cost $12,000 per square meter to build both the top and bottom; $17,000 per square meterto build the front; and $8000 pr square meter to build the remaining three sides.

how do i get an expression for the cost function in terms of x,y,and z ( the width, length, and height, respectively) for the total cost of the materials required?

Two stroke motors tend to have a statically set ignition point (generally at about 22 degrees BTDC) whereas a four stroke motor has an auto advance/retard mechanism with a static timing typically about 12 degrees BTDC. On a four stroke engine the advance unit is designed to allow for the burn time of the fuel/air mixture, which is relatvely constant, so that the spark must occur earlier the more the revs increase. Why is the same not true on a two stroke motor?
