Question

A glass cube of side length 5cm has a mass of 306.25g.

Answer 1

Answer:

2.45 g/cm3

Step-by-step explanation:

It's a cube, so all the side lengths are the same. It's volume is $(5cm)^3$ = $125 cm^3$.

At this point, we apply the definition of density $\rho = \frac mV$ where m is the mass and V the volume.$\rho = \frac{306.25g}{125 cm^3} = 2.45 g/cm^3$
