Term
| 3 methods to calculating surface area |
|
Definition
Each face - calculate the surface area of each face and add
Symmetry - caculate surface area of the front, back, top, bottom, and both sides and add
Overlap calculate surface area of all cubes the subtract number of faces touching (only works wuth cubes) |
