How do you figure area of solid figures?

Answer 1

-- You can only do one solid figure at a time.

-- Pick one solid figure to work on.

-- Stare at it for a while. In your mind, look at all of its flat faces,

even the ones you can't see in the picture.

-- One at a time, write down the area of each flat face.

-- When you have them all, add up all the areas of the flat faces.

-- The sum of all the faces is the area of the whole solid figure.

If you're doing this in the second grade, then you must be

pretty smart. I'm proud of you.
