Length of iron sheet 1m width 80cm height 1mm Determine the mass of the sheet if the density of iron is 7800kg / m3.

To find the mass of an iron sheet, multiply the density of the iron by the volume of the sheet (m = ρ * V).
Let’s calculate the volume by multiplying the length by the width and by the thickness, but first let’s translate everything into meters.
80 cm = 80 * 0.01 m = 0.8 m.
1 mm = 0.001 m.
Then, V = 1 m * 0.8 m * 0.001 m = 0.0008 m3.
Substitute the density and volume values into the formula for finding the mass, calculate.
m = 7800 kg / m3 * 0.0008 m3 = 6.24 kg.
Answer: the mass of an iron sheet is 6.24 kg.
