Take $1/undefined$$1/undefined$ of 7 this is a cubit.

The result is 5 palms 1 ﬁnger. This is its seked.

Problem 59B

If the seked of a pyramid is 5 palms 1 finger per euhit and the side of its base 12 cubits long, what is its altitude?

Multiply 5 palms 1 ﬁnge-r doubled, which is 10$1/undefined$, so as to get 1 cubit; a cubit is 7 palms. $1/undefined$ of 10$1/undefined$ is 7; therefore $1/undefined$ of 12, which is 8, is the altitude.

Problem 60

If a pillar (?) is 30 cubits high and the side (diameter?) of its base 15 cubits, what is its seked?

Take $2/3$ of 15; it is 7$1/undefined$. Multiply 30 so as to get 7$2/3$; the result is $1/undefined$.

This is the seked.
