A solid silver paperweight in the form of a square pyramid is shown below. If silver costs $0.12 per cubic centimeter, how much would it cost to manufacture 6 paperweights?

The cost to manufacture 6 paper weight is $232.32

where

b = base

h = height

Therefore,

v =  1 / 3 × 8.8² × 12.5

v = 1 / 3 × 77.44 × 12.5

v = 968 / 3

v = 322.666666667 cm³

1 cm³ = $0.12

322.67 cm³ = ?

cost of a paperweight = 322.67 × 0.12 = $38.72

Therefore,

1 paper weight = $38.72

6 paper weight = ?

cross multiply

cost of 6 paper weight = 6 × 38.72

cost of 6 paper weight = $232.32

It would cost $232.32, this answer is rounded.

Step-by-step explanation:

The formula for the volume of a square pyramid is:

So its just:

Then you just multiply the volume by the cost per cubic centimetre:

After just multiply the cost of one by how many you want, which is 6:
