Explanation:

Question 19 (Ruler Length Conversion)

Step1: Identify conversion factor

1 inch = 25.4 mm, ruler length = 12 inches.

Step2: Calculate length in mm

Multiply inches by mm per inch: \( 12 \times 25.4 \)
\( 12 \times 25.4 = 304.8 \)

Step1: Identify conversion factor

1 gallon = 3.8 liters, water used = 785 gallons.

Step2: Calculate liters used

Multiply gallons by liters per gallon: \( 785 \times 3.8 \)
\( 785 \times 3.8 = 2983 \)

Answer:

C. 304.8 mm
