Accepted Answer

# Answer:
1) millimeter / centimeter / decimeter / meter / dekameter / kilometer
2) 1 kilogram
3) 1 kilometer
4) 0.0012 g/cm³
5) 0.92 g/cm³
6) 1 g/cm³
7) 7.8 g/cm³
8) 19.3 g/cm³
9) 4080 g
10) 61.9 cm³
16) 45
17) 45; 0.75
18) 165

# Explanation:
## 1) Order metric length units
Metric prefix values: 1 km=10³m, 1 dam=10m, 1m=1m, 1dm=0.1m, 1cm=0.01m, 1mm=0.001m. Order from small to large: millimeter < centimeter < decimeter < meter < dekameter < kilometer.

## 2) Convert pounds to grams
1 pound ≈ 453.592g, so 2 pounds ≈ 907.184g ≈ 1kg.

## 3) Convert miles to meters
1 mile ≈ 1609.34m ≈ 1km.

## 4) Calculate air density
Density = mass/volume = 450000g / 375000000cm³ = 0.0012g/cm³.

## 5) Calculate ice density
Density = 200000g / 217391cm³ ≈ 0.92g/cm³.

## 6) Calculate water density
Density = 760g / 760cm³ = 1g/cm³.

## 7) Calculate iron density
Density = 4290g / 550cm³ = 7.8g/cm³.

## 8) Calculate gold density
Density = 1000g / 51.8cm³ ≈ 19.3g/cm³.

## 9) Calculate mercury mass
Mass = density×volume = 13.6g/cm³×300cm³ = 4080g.

## 10) Calculate silver volume
Volume = mass/density = 650g / 10.5g/cm³ ≈ 61.9cm³.

## 16) Convert hours to minutes
3/4 hour × 60min/hour = 45min.

## 17) Convert seconds to minutes/hours
2700s / 60s/min = 45min; 45min / 60min/hour = 0.75hour.

## 18) Convert kg to pounds
75kg × 2.2lb/kg = 165lb.
