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

Density is <u>mass</u>
volume
With those dimensions, the volume of the pyramid is;
V = lw(h/3)
V = (5)(6)(8/3)
V = 80 cm^3

D = <u> 40 g </u> = 1 g/cm^3
80 cm^3

If a person bought 8 items and each item was priced at $4, that means the total amount spent was $32.

$(8)(4)=32$

The person received 8 dollars in change. This means that the person payed 8 dollars more than what they spent. Well, we just found out how much they spent, so we can find out how much money the person gave the vendor.

Let p = amount of money paid by the person.

$32+8=p$
