Question

A sample of iron has the dimensions of 2 cm x 3 cm x 2 cm. If the mass of this
rectangular-shaped object is 94 g, what is tne density of iron?

Answer 1

Answer:

The density of iron is 7.833 g/cm³.

Explanation:

Mass of the object = 94 g

Dimensions = 2cm × 3cm × 2cm

therefore,

volume of the object = 2cm×3cm×2cm

                                    = 12cm³

so, density of iron =  $\frac{mass}{volume}$

                              = $\frac{94 g}{12 cm}$₃

                              = 7.833g/cm³
