Question

What is the length of the side of an iron ingot that has a mass of 4.578 kg and has width = height = 5.00 cm

Answer 1

density = mass/volume

let's assume this ingot is a rectangular prism for the sake of simplicity

therefore

density = mass/(length * width* height)

plug in density, mass, width, and height to find length. You will need to look up the density of iron, preferably in kg/cm^3 although if you find it in different units it's ok, just convert the length/mass to the appropriate units
