Area = 8*24 =192 square feet
Perimeter = 24+24+8+8 = 64 feet
192ft squared
1 cubic foot = 12 * 12 * 12 = 1728 cubic inches. > 2 * 8 * 1 = 16 cubic inches > 16 / 1728 = 0.00926 cubic feet.

221 feet is the greatest depth..... below are some figures to give you an idea of what depths (literally) they had to go to: Maximum depth below mean sea level Northern Line, just south of Waterloo station 21.3m (70ft) Maximum depths below ground level Deep-level tube lines Northern Line, Holly Bush Hill, Hampstead 67.4m (221ft) Sub-surface cut & cover lines East London Line, Wapping 18.29m (60ft) Average depths below ground level Deep level tube lines 24.4m (80ft) Sub-surface cut & cover lines 7.3m (24ft) Deepest station Hampstead 58.5m (192ft) below ground level I hope you enjoy the research, cheers, Skunkfarmer - New Hampshire USA
