Question

Rolls of foil are 304 mmmm wide and 0.014 mmmm thick. (The density of foil is 2.7 g/cm3g/cm3 .) What maximum length of foil can be made from 1.06 kgkg of foil?

Answer 1

92.2 m

Step-by-step explanation:

Given that:=

The breadth = 304 mm

Height = 0.014 mm

Let Length = x mm

Volume =
`Length* breadth* height`

Thus,

Volume =
`304* 0.014* x\ mm^3=4.256x\ mm^3`

Also, 1 mm³ = 0.001 cm³

So, volume = 0.004256 cm³

Given that density = 2.7 g/cm³

Mass = 1.06 kg = 1060 g

So,

`Volume=(Mass)/(Density)=(1060)/(2.7)\ cm^3=392.59\ cm^3`

So,

0.004256*x = 392.59

x = 92243.89 mm

Length of foil = 92243.89 mm = 92.2 m
