And another physics problem?

Question

3. in the bible, noah is instructed to build an ark 300 cubits long, 50 cubits wide and 30 cubits high. historical records indicate a cubit is equal to half a yard. (a) what would the dimensions of the ark be in meters? (b) what would the ark's volume be in cubic meters? to approximate, assume that the ark is to be rectangular.

Answer 1

all you have to do is convert units...

1 cubit = 1.5 yds/cubit x 3 ft/yd x 1/3.28 m/ft

1 cubit = 1.372 m

just multiply each length in cubits by this factor to get the length in meters

the volume of a rectangular solid is length x width x height, so just multiply the three dimensions to get volume in meter^3
