A) Using formula: length*width*height
= 1320ft^3
1320 * 62.4 = 823681bs
......................
B) Using formula: (Pi*r^2*h)*2 (height = 9ft)
= 14.1ft^3
14.1 * 62.4 = 879.8lbs
........................
C) Using formula: 4/3*Pi*r^3
Diam = 4ft = 33.51ft^3
33.51 * 62.4 = 2091.0lbs
Diam = 2ft = 4.19ft^3
4.19*62.4 = 261.5lbs
Diam = 1ft = 0.52ft^3
0.52 * 62.4 = 32.5lbs
Diam = 1/2ft = 0.07ft^3
0.07 * 62.4 = 4.4lbs
Hope this helps.
