Parallelepipeds!


We began our unit on 3D today with a review of vocabulary and a focus on prisms, learning how to calculate volume and surface area.  Do you remember the definition of parallelepiped?  Alysha H. does, as do her co-geometers Saeed L. and Valerie H.  Good work, guys - thinking about Geometry outside the box of the classroom!

I don't know why everyone was SO CHATTY today - it was like an epidemic.  Maybe someone can clue me in, but you know I am counting down until June 17- and I want EVERYONE  passing that exam!

Another note about HW #44 - some of the problems talk about triangular prisms, and we didn't practice solving any problems with prisms whose bases were not rectangles.  These problems may present a real challenge to you, but give them a try.  

JUST REMEMBER:
VOLUME of a PRISM  = AREA OF THE BASE x HEIGHT
SURFACE AREA of a PRISM = THE AREA OF ALL OF THE FACES ADDED TOGETHER

See you on the runway!
