According to Zaslavsky, despite the wide distribution of peoples and the existence of about a thousand languages in Africa, the words for two, three and four are similar in an area covering about half of the continent. This area includes the Sudan—the region extending from the Sahara southward to the Gulf of Guinea, and from the Atlantic Ocean to the River Nile—and most of the southern part of the continent now inhabited by Bantu-speaking people.
Gerdes (1999:55-56) observes that in Mozambique, to fasten a cover of a basket, two plaited strips with little lassos at their ends are permanently fixed to the cover, and two cubic buttons are fastened to opposite sides of the basket. Each of the lassos is pulled down around the corresponding button in order to close the basket. Two strips of a palm leaf are used to weave a button. Once an initial knot is made, one continues, on the backside, to weave “one-over-one-under,” building up successive layers of the button, until it has become more or less cubic.
R. Fletcher discusses Problem 10 of the Moscow Papyrus on the surface area of a basket and is perceived by some mathematicians to compute the surface area of a hemisphere. Fletcher examines which units might have been utilized in the problem and proffers the postulate that the basket in question was in reality hemispherical and was designed to hold 100 Hekat of corn. Furthermore, he points out that the units utilized in ancient Egypt appear to have some interesting geometrical properties. An example is that a circle with a radius of 1 pes (or 1 “foot” = 16 digits) was approximately equal in area to a square with sides measuring 1 royal cubit.
