A perfume bottle is in the shape of a cube. Each of its dimensions is 2 cm. If the perfume cost is $65 per ounce how much does this bottle of perfume cost? (1 ounce = 8 cm cubed) A) $130 B) $65 C) $48.75 D) $32.50

Answer :

We are told that 1 ounce = 8 cubic cm and the cost is $65 per ounce. Therefore, we need to first find the volume of the perfume bottle.

The volume of the cubic perfume bottle is the product of its side lengths

[tex]volume=2\operatorname{cm}\times2\operatorname{cm}\times2\operatorname{cm}[/tex][tex]volume=8\operatorname{cm}^3[/tex]

The volume of the perfume bottle is 8 cubic cm and since we know that

1 ounce = 8 cubic cm

and 1 ounce = $65,

the perfume costs $65 and therefore, choice B is correct.
