Answer 1

• Length=14ft=L
• Breadth=B=9ft
• Height =H=13ft

`\\ \rm\Rrightarrow TSA=2(LB+BH+LH)`

`\\ \rm\Rrightarrow TSA=2(126+117+182)`

`\\ \rm\Rrightarrow TSA=850ft^2`

Answer 2

We know that:

• 
  `L = 13 \ feet`
• 
  `B = 14 \ feet`
• 
  `H = 9 \ feet`

`Surface \ area = 2LB + 2BH + 2LH`

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

• 
  `Surface \ area = 2LB + 2BH + 2LH`
• =>
  `Surface \ area = 2(13)(14) + 2(14)(9) + 2(13)(9)`

Step-2: Find the surface area.

• =>
  `Surface \ area = 2(13)(14) + 2(14)(9) + 2(13)(9)`
• =>
  `Surface \ area = 364 + 252 + 234`
• =>
  `\bold{Surface \ area = 850\ feet^(2)}`
