Surface Area Formula: 2LW * 2LH * 2WH
------------------------------------------------
2LW:
5 x 1 = 5
5 x 2 = 10
------------------------------------------------
2LH:
4 x 1 = 4
4 x 2 = 8
------------------------------------------------
2WH:
5 x 4 = 20
20 x 2 = 40
------------------------------------------------
Surface Area:
40 + 8 + 10= 58
------------------------------------------------
Answer:
D) 58 cm2
