sheetLength = 1000 mm
sheetWidth = 500 mm
partLength = 100 mm
partWidth = 80 mm
gap = 5 mm

columns := floor((sheetLength+gap)/(partLength+gap))
rows := floor((sheetWidth+gap)/(partWidth+gap))
count := columns*rows
utilization := count*partLength*partWidth/(sheetLength*sheetWidth)

check utilization target: utilization >= 0.7

scenario alternative: sheetLength = 800 mm
