FTCE General Knowledge Math Practice Test

Which unit of measurement is equal to 3 feet?

1. Meter

2. Inch

3. Yard

4. Millimeter

The correct answer is: Yard

Three feet is equal to one yard. In the imperial system, a yard is defined as exactly three feet. This makes it a straightforward conversion, as you can visualize that a yardstick, commonly used for measuring length, is exactly the length of three 12-inch segments (which is one foot each). The other units listed do not equal three feet. A meter is longer than three feet, while an inch is much shorter, and a millimeter is significantly smaller than an inch, making them unsuitable for equating with three feet. Thus, the yard is the correct choice, directly aligning with the conversion of feet to yards in measurement terms.
