Question

The net of a rectangular prism and its dimensions are shown in the diagram.

What is the total surface area of the rectangular prism in square meters?

Answer 1

642.96

Explanation:

To find the surface area"

`SA=2lw+2lh+2wh`

Insert measurements into the equation:

`SA=2*17(2)/(5)*3+2*17(2)/(5)*13.2+2*3*13.2`

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

• 
  `2*17(2)/(5)*3= 104.4`
• 
  `2*17(2)/(5)*13.2=459.36`
• 
  `2*3*13.2=79.2`

Next: Addition

• 
  `104.4+459.36=563.76`
• 
  `563.76+79.2=642.96`

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
