Measurements by Joel A. Foner 10/97-1/98
Notes: Samples were weighed using an Ohaus beam balance (0.01 gm accuracy)
Balsa weights weights were calculated based on the listed density (lb / cu ft)
" (6 lb / cu ft = 1.575 gm / cu in, 4 lb / cu ft = 1.05 gm / cu in)"
"*** Micafilm requires an adhesive, which is not included in these measurements" |
