Question

An object has a length of 5.0 cm, a height of 3.0 cm and a width of 15.0 cm. It has a mass of 24 grams. What is its density?
A)225
B)9.4
C)0.11
D)2.25

Answer 1

density equals mass by volume

volume =l*b*h=5*3*15=225

mass is given

so density is 24/225

which is =.11

Answer 2

volume=5×3×15=225cm3
mass=24g
density=m/v=225/24g/cm3
