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.

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.
