Question

A student needs to find the density of a cube. each side of the cube measures 3 cm and the mass of the cube is 12g. what is the approximate density of the cube?

A. 0.4g/cm3
B. 2.25g/cm3
C. 4.0g/cm3
D. 36g/cm3

Answer 1

Density = 0.4g/cm³

Step-by-step explanation:

Given

Mass = 12 g

Length = 3 cm

Required

Determine the density.

To calculate density, we need volume.

Volume of a cube is:

Volume = Length ³

Hence:

Volume = (3cm)³

Volume = 27cm³

Density = Mass/Volume

Density = 12/27

Density = 0.4g/cm³ --- Approximated
