Excerpt from Publications of the Astronomical Society of the Pacific, 1899, Vol. 11 The planet is an oblate ellipsoid, whose equatorial diameter is about miles, and the polar diameter some twenty miles less. The integral calculus gives the volume of such a solid as some thing over 38% billion cubic miles, and the exact figures being reduced, make the result a little more than sextillion cubic feet. As has already been stated, one cubic foot of water at the Earth's surface weighs 62% pounds. The average cubic foot of the ...

Excerpt from Publications of the Astronomical Society of the Pacific, 1899, Vol. 11 The planet is an oblate ellipsoid, whose equatorial diameter is about miles, and the polar diameter some twenty miles less. The integral calculus gives the volume of such a solid as some thing over 38% billion cubic miles, and the exact figures being reduced, make the result a little more than sextillion cubic feet. As has already been stated, one cubic foot of water at the Earth's surface weighs 62% pounds. The average cubic foot of the Earth weighs 5. 58 times as much, or 348% pounds. But the density of Mars being only 73 per cent, and surface gravity one cubic foot of that planet, weighed upon its own surface, would give a result of 9694 pounds. Multiplying this by the volume in cubic feet, we find that Mars weighs just a little short of 550 sextillion pounds - that is, fifty-five with twenty-two ciphers annexed.
