Question

what is the density of the cube below if the mass is 24g?
h = 2cm
w = 2cm
l = 3cm

Explanation:

Step1: Calculate the volume of the cube

The volume formula for a rectangular - prism (assuming the cube - like shape is a rectangular prism with length \(l = 3cm\), width \(w=2cm\), height \(h = 2cm\)) is \(V=l\times w\times h\).

$$V=3\times2\times 2=12cm^{3}$$

Step2: Calculate the density

The density formula is \(
ho=\frac{m}{V}\), where \(m = 24g\) (mass) and \(V = 12cm^{3}\) (volume).

$$ ho=\frac{24g}{12cm^{3}}=2g/cm^{3} $$

Answer:

\(2g/cm^{3}\)
