Find the surface area of the rectangular box below

Answer:
SA = 206 ft.²
Step-by-step explanation:
Surface Area (SA) of a cuboid: 2(lw) + 2(wh) + 2(hl)
SA = 2(lw) + 2(wh) + 2(hl)
Substitute the given values and multiply:
SA = 2(lw) + 2(wh) + 2(hl)
SA = 2(13)(3) + 2(3)(4) + 2(4)(13)
SA = 2(39) + 2(12) + 2(52)
SA = 78 + 24 + 104
SA = 206 ft.²
Hope this helps!
