Answer:

Surface Area = 392 cm²

Step-by-step explanation:

Green (front):

SA = 1/2bh

= 1/2 (12) (8)

= 48 cm²

Green (left side):

SA = bh

= 5 (10)

= 50 cm²

Green (right side):

SA = bh

= 5 (10)

= 50 cm²

Green (back):

SA = 1/2bh

= 1/2 (12) (8)

= 48 cm²

Blue (front):

SA = bh

= 12 (4)

= 48 cm²

Blue (left side):

SA = cm²

= 5 (4)

= 20 cm²

Blue (right side):

SA = bh

= 5 (4)

= 20 cm²

Blue (back):

SA = bh

= 12 (4)

= 48 cm²

Blue (bottom):

SA = bh

= 12 (5)

= 60 cm²

Total:

48 + 50 + 50 + 48 + 48 + 20 + 20 + 48 + 60 = 392 cm²
