Answer:

614

Step-by-step explanation:

15 x 13 = 195 two times 195 x 2 = 390

4 x 15 = 60 two times 60 x 2 = 120

4 x 13 = 52 two times 52 x 2 = 104

104 + 120 + 390 = 614

Answer:

SA = 2(l·w)+2(w·h)+2(l·h)

SA = 614 sq in

Step-by-step explanation:

SA = 2(4x13)+2(13x15)+2(4x15)

= 2(52)+2(195)+2(60)

= 104 + 390 + 120

= 614
