Answer:3.84x10^10
Step-by-step explanation:

3.19=3.4+2.1c3.4+2.1c c= -1/44 = -0.02272...
-- The top and bottom are each 3" x 5" = 15in² each.
-- The front and back are each 9" x 5" = 45in² each.
-- The left and right sides are each 3" x 9" =27 in² each.
-- So the whole thing is (2 x 15in²) + (2x 45in²) + 2x (27 in²) = 174 in² .
