8 A quadrangular trapezoid 48 cubits in length, 10 cubits (sic! understand “fingers”) in width, 5 fingers in thickness, 2 fingers at the top. We proceed as follows. I add the width and the top, 10 and 2, totals 12, half of which is 6. Once more we multiply by 5 of the thickness, totals 30. (Multiply) by the length of 48 cubits, the result is 1,440. (Divide) by 192 and (convert) the remainder into fingers. The result is 7 (sc. solid cubits) and 12 fingers. This way for similar cases.

5 I do it the following way: I add the width, 16 and 12, totals 28, half of which is 14. We add the thickness, 6 and 8, totals 14, half of which is 7. (Multiply) by 14, totals is 98. (Multiply) by the length of 28 cubits, the result is 2,744. This I divide by 288 and divide the remainder in 12 fingers (sc. divide the remainder by 12 to convert into fingers). The result is 9 (sc. solid cubits) and 12 2/3 fingers. This way for similar cases.
