Question

1. What is the density of a cube with side 20cm, and mass 500g?​

Answer 1

Answer:

please add brain list.

Explanation:

First- You Calculate The Volume Of the Cube i.e. V= a³

First- You Calculate The Volume Of the Cube i.e. V= a³Therefore, this particular cube has a side 5 cm.

First- You Calculate The Volume Of the Cube i.e. V= a³Therefore, this particular cube has a side 5 cm.V=(5)³, V=125 cm³

First- You Calculate The Volume Of the Cube i.e. V= a³Therefore, this particular cube has a side 5 cm.V=(5)³, V=125 cm³Second- You use the Density Formula i.e Density= Mass/Volume.

Answer 2

Explanation:

density = mass/volume

but for MKS

mass = 500/1000 = 0.5 Kg

side = 20/100 = 1/5 = 0.2m

volume of cube = (0.2)³

= 0.008m³

density of cube = 0.5/0.008

= 62.5 kg/m³
