The depth of the ocean is sometimes measured in fathoms (1 fathom = 6 feet). Distance on the surface of the ocean is sometimes measured in nautical miles (1 nautical mile = 6076 feet). The water beneath a surface rectangle 3.70 nautical miles by 2.80 nautical miles has a depth of 28.0 fathoms. Find the volume of water (in cubic meters) beneath this rectangle.

Please help, I know I have conversion factor. but I just cant get the right result.

1ft=.3048m
1cubic ft= (.3048)^3 meters^3

so in meters cubed, the volume=
3.70*6076ft * 2.8*6076ft * 26*6ft * (.3076)^3 m^3/ft^3
