Area = 1/2*(14+12)*8 = 104 square cm
Surface area = 2*(12*8 + 8*9 + 9*12) sq cm = 2*(96 + 72 + 108) = 552 cm2

It depends on the exact configuration of the shape.

there are too many dimensions for me to hazard a guess at the shape of it.

The area of a circle with a diameter of 8 centimeters is: 50.27 square centimeters.
8*6*8 = 384 cubic cm
12*8*9 = 864 cubic cm
The area of rectangle is : 9.6
