Solution:

We know that:

  • [tex]L = 13 \ feet[/tex]
  • [tex]B = 14 \ feet[/tex]
  • [tex]H = 9 \ feet[/tex]

[tex]Surface \ area = 2LB + 2BH + 2LH[/tex]

Step-1: Substitute the length, breadth, and height.

  • [tex]Surface \ area = 2LB + 2BH + 2LH[/tex]
  • => [tex]Surface \ area = 2(13)(14) + 2(14)(9) + 2(13)(9)[/tex]

Step-2: Find the surface area.

  • => [tex]Surface \ area = 2(13)(14) + 2(14)(9) + 2(13)(9)[/tex]
  • => [tex]Surface \ area = 364 + 252 + 234[/tex]
  • => [tex]\bold{Surface \ area = 850\ feet^{2}}[/tex]
  • Length=14ft=L
  • Breadth=B=9ft
  • Height =H=13ft

[tex]\\ \rm\Rrightarrow TSA=2(LB+BH+LH)[/tex]

[tex]\\ \rm\Rrightarrow TSA=2(126+117+182)[/tex]

[tex]\\ \rm\Rrightarrow TSA=850ft^2[/tex]
