%X This article presents numerous examples of an erroneous conception, stating that the ¡°total force¡± by which a fluid acts on an immersed body is equal to the product of corresponding fluid pressure and the body¡¯s surface area. This conception, which started its long life at the beginning of XVIII century, still appears in today¡¯s physics textbooks published in different countries for different educational levels. It is formulated either as an ¡°astonishing fact¡± or should be ¡°discovered¡± through students¡¯ calculations. In the last case, students¡¯ knowledge may be unnecessary fragmented. Finally, a few differences between cultures of school and research physics are shortly discussed.
