Question: Each edge of a cubical block of wood measures 2 inches. What is the surface area of the block in square inches?
Answer: 4.
I thought answer was 8. Why is it 4 and not 8? I thought it was 2x2x2. If that gives volume and not surface area, then wouldn't surface area be the sum of all six sides therefore 2x6=12? How do you arrive at 4? Do they mean what is the surface area of one side of the block? But that would be 2x2. Ugh. I'm so confused. And I don't see how it can be 1+1+1+1 if each edge is 2. Please help!
Thank you.
