Answer:

1553 cm^2.

Step-by-step explanation:

Surface area of the top part = area of the lateral part of the cylinder + area of the top circle

= 2π*6*10 + π*6^2 = 490.09 cm^2

Surface area of the bottom part

= surface area of the cube - surface area of the bottom of the cylinder

= 6 * 14^2 - π*6^2 = 1062.90

Total surface area = 490.09 + 1062.90 = 1553 cm^2.
