Diya Swanson · Answer 1

Density is mass/volume or g/cm^3 in this case

vpyramid = (1/3) lwh

given

l=6

w=5

h=8

V = (1/3) 6*5*8

V=2*40

V=80cm^3

mass=40g

density=40g/80cm^3=0.5g/cm^3

0.5 grams per cm^3 is the density

Ean Alvarez · Answer 2

Density is mass

volume

With those dimensions, the volume of the pyramid is;

V = lw (h/3)

V = (5) (6) (8/3)

V = 80 cm^3

D = 40 g = 1 g/cm^3

80 cm^3
