Answer:
0.4752 oz.
Explanation:
Length = 1000 ft
Converting ft to inches,
12 in = 1 ft
1000 ft = 1000 * 12
= 12000 in
0.05082 in = 0.12908 cm
Mass = 19.8 lb
Converting lb to oz,
1 ounce = 0.0625 lb
1 lb = 1/0.0625 oz
19.8 lb = 1/0.0625 * 19.8
= 316.8 ounce
Since, 12000 in of copper wire weighs 316.8 ounces.
Therefore, 1 in will weigh = 316.8/12000
= 0.0264 oz
18 in = 0.0264 * 18
= 0.4752 oz.
A system of measurement that is used to determine volume, distance and mass is called a metric system. Foot and inches are used for measuring length while ounces and pounds are used to mass.
18 inches of the wire weigh 0.4752 oz.
This can be estimated as:
Given,
- Length = 1000 ft
Converting feet (ft) to inches (in),
12 in = 1 ft
[tex]1000 ft = 1000 \times 12[/tex]
1000 ft = 12000 in
- Mass = 19.8 lb
Converting lb to ounces (oz),
1 ounce = 0.0625 lb
[tex]1 lb = \dfrac{1}{0.0625} oz[/tex]
[tex]19.8 lb = \dfrac{19.8}{0.0625}[/tex]
Mass = 316.8 ounce
∵ 12000 in copper wire weighs 316.8 ounces.
∴ 1 inch will weigh = [tex]\dfrac{ 316.8}{12000}[/tex]
Mass = 0.0264 oz
[tex]18 \:in = 0.0264 \times 18[/tex]
Mass = 0.4752 oz
Therefore, 18 inches of wire will weigh 0.4752 oz.
