Question

HELP! Use the net to find the surface area of the prism.

Answer 1

290 mm

Explanation:

Since you have the three side lengths needed, all you need to do is use the formula 2[(lh)+(wh)+(lw)].

So it would look something like this --> 2[(3*11)+(3*8)+(11*8)]

This gives you 2[(33)+(24)+(88)]

Now you have 2(145)

And your final answer is --> SA = 290
