We can't help you because your problem appears to have an error.

As you stated it, the problem can not be solved.

This is Cayla's mom, it really has it in her book. This is one of those tricky answers hopefully...Thank you for helping us.
Answered by Ms. Sue
It's not a tricky answer. It's a mistake. Have Cayla check with her teacher about it.

Also, solids are not generally considered to have perimeters. They have volume and surface area.

I guess the sum of the 12 edges could be considered a perimeter, but it's an unusual terminology.
