find the surface area of the rectangular prism 9in.x 9in.x 12in
----------------
rectangular prisms have 6 sides. The sides are pairs, 2 of each area.
For a prism with sides a, b and c, the area is
2ab + 2ac + 2bc
-------------
For this one:
A = 2*9*9 + 2*9*12 + 2*9*12
A = 162 + 216 + 216
A = 594 sq inches
