Answer:

642.96

Step-by-step explanation:

To find the surface area"

[tex]SA=2lw+2lh+2wh[/tex]

Insert measurements into the equation:

[tex]SA=2*17\frac{2}{5}*3+2*17\frac{2}{5}*13.2+2*3*13.2[/tex]

Now to go through the very tedious steps of actually solving the equation (we got this!)

  • [tex]2*17\frac{2}{5}*3= 104.4[/tex]
  • [tex]2*17\frac{2}{5}*13.2=459.36[/tex]
  • [tex]2*3*13.2=79.2[/tex]

Next: Addition

  • [tex]104.4+459.36=563.76[/tex]
  • [tex]563.76+79.2=642.96[/tex]

And we have our answer!

I hope this helps and please feel free to comment, give feedback, ask questions, and correct me if I am wrong!

Have a great day
