Question

Alexis bought a pyramid-like paperweight for her teacher. The paperweight has a volume of 200 cm3 and a density of 1.5 grams per cubic centimeter.

What formula you would you use to find the density of the paperweight?
How much does the paperweight weigh?

Answer 1

The density is equal to the weight divided by the volume:

`\rho=(W)/(V)`

The paperweight weights 300 grams.

Explanation:

The density of the paperweight can be calculated knowing the weight and the volume of this paperweight.

The density is equal to the weight divided by the volume:

`\rho=(W)/(V)`

We know that the density of this paperweight is 1.5 grams per cm3, and its volume is 200 cm3.

We can use the formula of the density to calculate the weight:

`\rho=(W)/(V)\\\\\\W=\rho\cdot V=1.5\;(g)/(cm^3)\,\cdot\;200\; cm^3\\\\\\W=300\;g`

The paperweight weights 300 grams.
