Question

Mass = 80 g
Length of side = 2cm what’s the density

Answer 1

10g/cm^3

Explanation:

Density is calculated by dividing the mass over volume.

d = m/v ( where d is density,

m is mass and

v is volume).

In this question, the value for volume is unknown as we were only given length.

STEP 1:

so we find volume first by using the length of side given.

Volume of a cube = (length of side )^3

volume = (2cm)^3 , volume = 2cm x 2cm x 2cm = 8cm^3

STEP 2:

we put the value for volume into the density formula'

d = mass / volume

d = 80g / 8cm^3

d = 10g/cm^3
