### 1) 17 AAA batteries

The triple-A batteries are usually used by us for inserting in the battery run tools. These triple-A batteries are known to use less power and they are about the length of 1.75 inches. Thus we shall note that with simple calculations that about 17 batteries shall be required for estimating the length of 30 inches. These batteries are obtained in any grocery store and thus you can easily observe 17 such batteries to obtain a length of 30 inches. These triple-A batteries are shorter than the double-A batteries but are good to cite as an example for estimating the length of 30 inches.

### 2) 30 Paper clips in a row

The paper clips are usually required for collecting papers and accumulating them systematically. The paper clips are a useful object as a part of our stationery tools and you must have come across them everywhere. These paper clips are usually of the length of 1 inch. Thus if you can align thirty such paper clips in a row and you shall be able to observe the length of 30 inches. You may get a straight line if you arrange these thirty paper clips in a row.

### 3) 2 Bowling pins

You must have spotted a bowling pin in the bowling alley. You shall notice that in a bowling alley, the lane is laid, and at the end of the lane, the bowling pins are kept and the player has to roll the balls to hit the pins.

### 15) 15 Golf Tees

The golf tees are usually of the length of 2.1 inches and thus you shall observe them in a line to estimate 30 inches. Hence to be precise you shall be needing 15 such golf tees to align them along a straight plane and then observe the length of the line which is about 30 inches. Golf tees are generally available in the spirits shop or if you are a golf player you might have come across them several times. Thus we can cite this example to explain the length of 2.5 ft in real life with frequently spotted objects around us.

Diameter is described as the line joining the end to end of the circle, without a bend and passing through the center. These American pennies have a diameter of about 0.75 inches each and if you take 40 such American pennies and align them in a straight line then the length of such a line will be 30 inches.

### 18) 5 iPhone XR models

We have all seen a model of the iPhone in the newspaper, in advertisements, or may own one. These iPhone XR models are approximately the length of 5.94 inches which are made to stay constant during the manufacture of this particular model.

This is also a good example that you may spot for realizing the length of 30 inches.

### 19) Two-fifth as tall as a Refrigerator

Side-to-side refrigerators are standardized to a height of about 70.50 inches. Hence it is easy for you to observe the height of the refrigerator and estimate the length of 30 inches which is about 2/5th the height of the model. The different companies have different preferences for making the models but a generalized size can be taken into account for estimating the length of 30 inches in real life. You can take this as an example to explain the length of 30 inches with objects around us.
