a geographical map
A contour map, possibly.
It's about 25-30 percent land.
You cannot get the square footage of land which is measured in 5 dimensions. In fact I am not sure where you would find 5-dimensional land.
Land 261914 sq. mi.
By area - its the 4rd largest land mass.

There can be no answer. Square acre is a measure in 4-dimensional hyperspace. Land is not 4-dimensional and we cannot perceive 4-d space.
Earth is three-dimensional, but maps are two-dimensional.
"All the land surface of the earth."...
Land-surface datum is a datum plane that is approximately at land surface at each well. If known, the elevation of the land-surface datum above sea level is given... Datum: any level surface, line, or point used as a reference in measuring elevations.
Land covers about 30% of the Earth's surface, with the remaining 70% being covered by water bodies such as oceans and seas. Land consists of continents, islands, and other landmasses where humans and terrestrial organisms live and thrive.
Land is above the waterline. No surface currents can flow over land.
About 33% of the earth's land surface is covered by deserts. That's 1/3 of the surface.
About one third of the land surface of the earth is desert.
Collecting weather data over the sea and ocean surface from space is easier than from land surface because there are no obstacles like mountains or buildings to obstruct the view. The vast expanse of open water makes it easier to capture consistent data. Additionally, satellites can cover larger areas more efficiently, providing a broader perspective on global weather patterns.
No state covers 40% of the world's land surface.
