How much is 1% of level at 4 feet?

To determine how much 1% of a level at 4 feet is, you first need to convert the height into inches since the answer choices are in inches.

There are 12 inches in a foot, so 4 feet can be converted into inches as follows:

4 feet x 12 inches/foot = 48 inches.

Next, to find 1% of this amount, you multiply the total height in inches (48 inches) by 0.01 (which represents 1%):

0.01 x 48 inches = 0.48 inches.

This calculation shows that 1% of 4 feet is indeed 0.48 inches, confirming that the answer option provided is accurate. Understanding percentage calculations in this context is crucial for crane operation and safety, as precise measurements often impact weight distribution and load handling.
