Which nonstandard measurement unit is closest to a decimeter? the width of your hand or the length of your arm
A decimeter is 1/10 of a meter or 10 centimeters. That's about 4 inches. Which is closest to that measurement -- the width of your hand or the length of your arm?
A cell phone and a standard pen are about 1 decimeter long.
Please compare the length of your arm with a cell phone or a pen.
To determine which nonstandard measurement unit is closest to a decimeter, we can compare the width of a hand and the length of an arm to a decimeter. Here's how to do it:
1. Measure the width of your hand:
- Place your hand flat on a surface.
- Use a ruler or a measuring tape to measure the distance across your hand from the outer edge of your pinky finger to the outer edge of your thumb. This measurement represents the width of your hand.
2. Measure the length of your arm:
- Extend your arm fully.
- Starting from the shoulder, use a measuring tape or ruler to measure the distance from your shoulder to the tip of your middle finger. This measurement represents the length of your arm.
3. Compare with a decimeter:
- A decimeter is equal to 10 centimeters or 100 millimeters.
- Compare the measurements you obtained for the width of your hand and the length of your arm with a decimeter. If either of them is closer numerically to 10 centimeters or 100 millimeters, then that measurement would be closer to a decimeter.
Note that the result may vary from person to person, as hand and arm sizes differ among individuals.
