What is a Boabab, and how wide is it?

Answer 1

. IF you mean the baobab tree, and not the Irish black-metal rock group, "The species reach heights of between 5–25 m (exceptionally 30 m) tall, and up to 7 m (exceptionally 11 m) in trunk diameter. They are noted for storing water inside the swollen trunk, with the capacity to store up to 120,000 litres of water " .
a meter is 3 ft. So 7m diameter is close to 7 ft in width. .

Answer 2

It's a tree.
