Volume formulas review

The goal of this exercise was to review the formulas for the volume of prisms, cylinders, pyramids, cones, and spheres.

Notes:

## Rectangular prism: V=l•w•h

## Triangular prism: V=b•h•l / 2

## Cylinder: V=πr²h

## Cone: V=πr²h/3

## Sphere: V=4/3πr³

Volumes of cones, cylinders, and spheres

OH MY GOSH. This exercise was a struggle but luckily I was able to finish it and earn 550 energy points. I am just glad I took these notes, they really helped. I was also able to understand how to use the formulas and almost memorize what each of the formulas are.

30 min of work:

At the end of last class, I was able to finish all but one shape, after I finish this last shape, my project will be complete (besides me having to write up my notes).Well, I tried to attempt a sphere…not so good. I think I am just going to crumple paper into a ball and see where that leads me.

Yeah, I’m going to skip the sphere. I already have a cube, triangular pyramid, a cone, and cylinder. Seems good to me :p. The whole rest of class was alright, wish the sphere worked out.
