How many significant figures in 8000kg

There are four significant figures in 8000kg.

To determine the number of significant figures in 8000 kg, we follow these rules:

1. Non-zero digits are always significant.
2. Zeros between non-zero digits are always significant.
3. Leading zeros (zeros before the first non-zero digit) are not significant.
4. Trailing zeros (zeros after the last non-zero digit) may or may not be significant, depending on whether there is a decimal point present.

In this case, 8000 kg has four digits, all of which are non-zero. Therefore, all four digits are significant. There are no trailing zeros after the last non-zero digit, and there is no decimal point.

Thus, 8000 kg has four significant figures.
