Answer 1

Tristan has a total length of 10.5 feet or 126 inches of wood when all the pieces are converted to the same unit and summed together.

Step-by-step explanation:

To find the total length of wood that Tristan has, we must convert all lengths into the same unit, either inches or feet, and then add them together. Since most measurements are given in feet, let's convert all of them into feet before summing up.

• 6 inches = 0.5 feet (since 1 foot = 12 inches)
• 4 feet
• 30 inches = 2.5 feet
• 3.5 feet

Now, adding up all the lengths: 0.5 feet + 4 feet + 2.5 feet + 3.5 feet = 10.5 feet. To convert this into inches, multiply by 12 (since 1 foot = 12 inches): 10.5 feet * 12 inches/foot = 126 inches.

Therefore, the total length of wood Tristan has is 10.5 feet and 126 inches, which corresponds to options B and D.
