Answer:
840 inches
Step-by-step explanation:
Given that;
Each unit has a total of 6 shelves & each shelf holds 35 inches of filed charts
i.e number of shelf per unit = 6
Shelving unit shelf width = 35 inches
There are total of four 6-shelf units available
∴ To determine the total filling spaces in inches we have;
Total number of shell per unit × number of shelf per unit × Shelving unit shelf width
= 6× 35 × 4
= 840 inches
