What is 1 2 and 3 dimensional?

Answer 1

-- Anything that's 1-dimensional has length, but it's zero wide and zero high,

like a straight line.

-- Anything that's 2-dimensional has length and width, but it's zero high,

like a drawing of a square on paper.

-- Anything that's 3-dimensional has length, width, and height, like a flower,

an iceberg, a school bus, a paper airplane, or a house.
