We're dealing with a rectangular prism here buddy. The length, width and height gives it away.
OpenStudy (anonymous):
To find the volume, multiply the length, the width and the height.
OpenStudy (anonymous):
I don't know how to do that..
OpenStudy (anonymous):
Okay let's break it down. I'll give you a cookie when we're done.
OpenStudy (anonymous):
Yay! I love cookies
