Final answer:
To calculate units per linear foot of shelf space, first ensure all measurements are in the same unit, then use a ratio of the unit size to the shelf length to determine how many units fit in a linear foot.
Step-by-step explanation:
To find units per linear foot of shelf space, you need to consider the size of the units and the total length of the shelf. If you know the width of each unit (in inches) and the total length of the shelf (in feet), you can calculate how many units will fit within one linear foot of shelf space.
First, identify the object you are measuring and decide on the most appropriate unit of measurement; for shelf space, it's typically feet or inches. Next, convert all measurements to the same unit to make calculations easier. For example, if the size of a unit is given in inches, convert the shelf length to inches as well (1 foot = 12 inches).
Then, calculate the ratio of the unit size to the shelf size in inches and convert this ratio into the number of units per foot. If a unit is 4 inches wide and the shelf is 12 inches (1 foot), the ratio is 4 inches per unit/12 inches per foot, which simplifies to 3 units per linear foot.
