Yesterday in math, our class moved onto a new unit called SURFACE AREA. We started off by creating our new foldable which turned out to be a RECTANGULAR PRISM.
All rectangular prisms have :
- 6 faces
- 8 edges
- 8 VERTICES
TO DESCRIBE A 3D OBJECT, COUNT ITS FACES, EDGES, AND VERTICES
face- A face is a flat surface of a 3D figure. EXAMPLE:
vertex - A vertex is a point where two or more straight lines meet. EXAMPLE:
edge: Is the line where two surfaces meet. EXAMPLE :
Net : It is a 3 dimension shape, that is flattened. FOR EXAMPLE WHEN YOUR MAKING A CUBE, ONCE YOU FIRST GET THE LAYOUT.
RECTANGULAR PRISM : A rectangular prism is a solid 3D object that has 6 faces that are rectangles. IT CAN LOOK LIKE MANY DIFFERENT WAYS.
After we found out those definitions, we had to draw 3 different other kinds of rectangular prisms and make a chart to write down the similarities and differences of them:
Similarities : Each of those RPS have 6 faces, 6 sides, 8 edges, and 8 vertices. Differences : Each look different from each other but are the same. The dimensions are different, and the face sizes are different
Once we finished that, we had to finish page 48 in our homework book. The very last thing we had to do was go home and find 3 rectangular prisms from our house and draw the SIDE, FRONT, and TOP view of them. These are the objects I chose :
