Today in class we learned about Surface Area of a CUBE and RECTANGULAR PRISM.
BEFORE all that, we learned how many lines of symmetry a 3 dimensional cube has.
There are a total of 9 lines of symmetry.
( Sorry if the picture seems a pretty trippy to you. )
Surface Area of a Cube

Congruent means its the same shape and size.
