Calculate the total volume of material that will be removed when drilling the three holes. 3 The diagram shows a drill drift that is made from 4mm thick carbon steel. Diagram not to scale and all dimensions in mm (e) Calculate the volume of the drill drift. The cost of manufacturing the drill drift is calculated using the following formula: C = 4+m²t+nt Where C is the cost of the drill drift(s) (in dollars), m is the number of machining operations that need to be completed, t is the time taken to machine one drill drift in minutes, and n is the number of drill drifts being produced. (f) Rearrange the formula to make t the subject. (g) Calculate the time taken to machine one drill drift (n) when: C= $'Y' and m = 3
