Question

what is the density of the cube below if the mass is 50g?
h = 5cm
w = 1cm
l = 2cm
density

Explanation:

Step1: Calculate the volume of the cube

The volume formula of a rectangular - prism (cube - like shape here) is \(V = L\times W\times H\). Given \(L = 2cm\), \(W = 1cm\), \(H = 5cm\), then \(V=2\times1\times5\).

$$V = 10cm^{3}$$

Step2: Calculate the density

The density formula is \(
ho=\frac{m}{V}\). Given \(m = 50g\) and \(V = 10cm^{3}\), then \(
ho=\frac{50}{10}\).

$$ ho = 5g/cm^{3} $$

Answer:

\(5g/cm^{3}\)
