Today, students will use the knowledge learned in Day 7 to find out the volume of prisms, pyramids, cylinders, cones, and spheres in real life problems.
Prism
area of base × height
Cylinder
|
πr2h where r = radius, h = height
|
Cone
| 
where r = radius, h = height
|
Pyramid
|  |
or area of base x height
3
Sphere
| 
where r = radius
