Pesahim 109

How big is a revi’it?

Rav Hisda’s thesis:

Reviit log = 2 x 2 x 2.7  fingerbreadths = 10.8 cubic fingerbreadths

Proof from Baraita:

40 seah = 3 cubic amot

1 Seah = 6 kav = 24 log = 96 revi’it log volume measurements

40 seah = 3840 revi’it log

1 Amah = 6 tefah = 24 fingerbreadths distance measurements

3 cubit amot = 3 x 243fingerbreadths = 41,472 cubic fingerbreadths

3,840 revi’it log = 41,472 cubic fingerbreadths

1 revi’it log = 10.8 cubic fingerbreadths

1 amah = 19.2 inches

40 seah = 3 cubic amot = 3 x 19.23 inches = 21,234 cubic inches = 92 gallons

Revi’it = 92 gallons / 3840 = 11,776 fluid oz / 3840 = 3.06 oz
