# Question #0aa82

##### 1 Answer

#### Explanation:

The first thing I like to do is write down the important information and what I'm trying to find

length = 3 cm

width = 6 cm

height = 4 cm

mass = 80.0

Density = ??

Then I find the formula I need

The formula for density is

Do we have what we need? We have mass, but we don't have volume.

Can we use the information to find volume? Yes - if we multiply the length, width, and height together we can get the volume.

so

Plug in what you know

now that you know volume in your density formula

Going back to your questions to figure out how many digits your answers needs - since the smallest amount of digits is 2 (in 3.0) your answer should have two digits
