What is the surface area of the regular pyramid below

According to research, exposure to a certain type of bacteria called mycobacterium vaccae which is found in soil can help increase serotonin levels in the body. Serotonin is a chemical found in the brain. It can boost a person's mood and decrease anxiety. This same chemical can help people better process information in their brains. Just by being outside, our bodies can breathe in this bacteria. Research has shown that this bacteria appeared to boost the mood in laboratory mice. Additionally, the mice that were given this bacteria in their diet were able to move through a maze twice as quickly as mice that were not given this bacteria. These same mice also behaved less anxiously than the other mice.
