A 156-kg coil of sheet steel is 0.80 mm thick and 50 cm wide. How long is the steel in the coil?

Well, let's do some math circus here! We need to find the length of the steel in the coil. So, to find that, we can use the formula:

Length = Mass / (Thickness * Area)

Now, let's calculate it step by step. First, let's convert the thickness from mm to meters:

0.80 mm = 0.80/1000 = 0.0008 meters

Next, let's calculate the area of the sheet steel:

Area = Width * Thickness
Area = 50 cm * 0.0008 meters = 0.04 square meters

Finally, we can find the length of the steel in the coil:

Length = Mass / (Thickness * Area)
Length = 156 kg / (0.0008 meters * 0.04 square meters)

Do you want the answer in meters or feet?

To find the length of the steel in the coil, we can use the formula for the volume of a cylinder:

Volume = Area x Thickness

First, let's calculate the area of the sheet steel:

Width = 50 cm = 0.5 m (since 1 m = 100 cm)
Thickness = 0.80 mm = 0.0008 m (since 1 m = 1000 mm)

Area = Width x Thickness
Area = 0.5 m x 0.0008 m
Area = 0.0004 m^2

Next, we can calculate the volume of the coil of steel:

Volume = Area x Thickness
Volume = 0.0004 m^2 x 156 kg
Volume = 0.0624 m^3

Finally, we can find the length of the steel by dividing the volume by the area:

Length = Volume / Area
Length = 0.0624 m^3 / 0.0004 m^2
Length = 156 m

Therefore, the length of the steel in the coil is 156 meters.

To find the length of the steel in the coil, we can use the formula:

Length = (Mass / Area) / Thickness

First, let's convert the given measurements to the appropriate units:

Thickness = 0.80 mm = 0.80 / 1000 = 0.0008 meters (convert mm to meters)

Width = 50 cm = 50 / 100 = 0.50 meters (convert cm to meters)

Mass = 156 kg

Now, we can calculate the area of the steel coil:

Area = Width x Thickness = 0.50 meters x 0.0008 meters = 0.0004 square meters

Now, we can use the formula to find the length:

Length = (Mass / Area) / Thickness = (156 kg / 0.0004 square meters) / 0.0008 meters = 487,500 meters

Therefore, the length of the steel in the coil is 487,500 meters.

The volume of the steel in the coil is

V = Length*Width*Thickness
= (mass)/(density)

= 156 kg/7.9*10^3 kg/m^3
= 1.98*10^-2 m^3

Length = 1.98*10^-2/(0.5)(8*10^-4)
= 49.4 meters

I have used an "average" density for steel. If you know the alloy type, you can find a more accurate value.
