How many tubes of MITC-Fume are applied to a pole with an original circumference of 29 inches and a shell-rot circumference of 28.5 inches?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (C)

The number of MITC-Fume tubes needed is determined by how much of the pole’s circumference still needs treatment. The pole originally measures 29 inches around, but shell-rot has reduced the circumference to 28.5 inches, leaving a difference of 0.5 inches that must be covered. In this context, each tube provides coverage for 1/6 inch of circumference, so you divide the difference by 1/6: 0.5 ÷ (1/6) = 3. Therefore three tubes are required. This illustrates how a small reduction in circumference translates into the number of tubes needed to ensure complete coverage.
