Answer:

SA = 206 ft.²

Explanation:

Surface Area (SA) of a cuboid: 2(lw) + 2(wh) + 2(hl)

SA = 2(lw) + 2(wh) + 2(hl)

  • l = 13 ft.
  • w = 3 ft.
  • h = 4 ft.

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!
