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
