To determine the number of buckets of paint Hava will need to cover a total wall area of 422.7 square meters (m²), given that each bucket covers 110 m², we can follow these steps:
1. Calculate the exact number of buckets needed:
- Divide the total wall area by the coverage per bucket:
[tex]\[
\frac{422.7 \text{ m}^2}{110 \text{ m}^2/\text{bucket}} = 3.842727 \text{ buckets}
\][/tex]
2. Round up to ensure full coverage:
- Since you can't purchase a fraction of a bucket and you must cover the entire wall, you'll need to round up to the next whole number. Therefore, Hava will need:
[tex]\[
\text{4 buckets}
\][/tex]
3. Report the result to two significant digits:
- The whole number 4 is also expressed as two significant digits correctly since the leading non-zero digits count.
Thus, Hava will need 4 buckets of paint.
