Chapter 8.4 VOLUME of PRISMS in the geometry strand

Good Afternoon Ladies and Gentlemen,

The changing of the guard has happened- I am back! The last 3 chapters have been a bit more choppy and we will be finishing these, starting with the end of chapter 8 on Geometry. We will review in class the vocabulary as this is upmost important in math but especially in Geometry. But in this section we are looking at formulas ( shortcuts ) again and 3-D shapes, in particular, PRISMS. This is your first vocabulary term for this section. A prism is labeled by the bases, if the base is a rectangle, the prism is a rectangular prism. And if the base is a triangle, it is called a triangular prism. Prisms are everywhere: Cereal boxes, tents, wedges, and so on...... bet you can name many. Prisms is your second vocabulary term. And in this section we will find out the Volume of the prisms. That is how much the prism can hold if it were to be filled up. The formula for volume is V=BH (or V=LHW) for a rectangle prism or V= 1/2 BH ( 1/2 LWH) for a triangular prism. These formulas are similar to the formulas for rectangles and triangles. This sounds confusing, but hang on , watch the videos, take notes, and ask away with questions. Make sure you write in your vocabulary terms in your graphic organizer.
