An aerospace engineer is testing a newly fabricated composite casing to verify its material grade. The engineer's measurements determine the density of the composite sample to be 1.65±0.08 g/cm31.65 \pm 0.08\text{ g/cm}^31.65±0.08 g/cm3.
State the minimum and maximum values for the density of this composite sample.
Table 1 shows the reference densities for five different carbon-epoxy material grades.
Table 1
| Material Grade | Density in g/cm3\text{g/cm}^3g/cm3 |
|---|---|
| Grade 1 | 1.82±0.101.82 \pm 0.101.82±0.10 |
| Grade 2 | 1.90±0.051.90 \pm 0.051.90±0.05 |
| Grade 3 | 1.50±0.081.50 \pm 0.081.50±0.08 |
| Grade 4 | 1.40±0.061.40 \pm 0.061.40±0.06 |
| Grade 5 | 1.30±0.121.30 \pm 0.121.30±0.12 |
Which two material grades from Table 1 could be the composite sample the engineer tested? Explain your answer.
