STEP 1

Assumptions1. We are given the number $248.0$
. We need to determine the number of significant figures in this number3. We follow the rules of significant figures, which are - All non-zero digits are considered significant - Any zeros between significant digits are significant - Leading zeros are not significant - Trailing zeros in a number with a decimal point are significant

STEP 2

Identify the non-zero digits in the number.In $248.0$, the non-zero digits are $2$, $4$, and $8$.

STEP 3

Identify any zeros between significant digits.
In $248.0$, there are no zeros between significant digits.

STEP 4

Identify any leading zeros.
In $248.0$, there are no leading zeros.

STEP 5

Identify any trailing zeros in a number with a decimal point.
In $248.0$, there is one trailing zero after the decimal point.

STEP 6

Count the total number of significant figures.
The number of significant figures in $248.0$ is the sum of non-zero digits and any trailing zeros in a number with a decimal point.

Calculate the total number of significant figures.
The number of significant figures in $248.0$ is $3$ (from the non-zero digits $2$, $4$, and $$) plus $1$ (from the trailing zero after the decimal point), which equals $4$.
The number $248.0$ has $4$ significant figures.
