Cord [cd]
The cord is a traditional unit of volume used primarily in North America to measure stacked firewood.
It represents a neatly stacked pile of wood measuring 4 feet high, 8 feet long, and 4 feet deep.
Summary:
1 cord = 128 ft³ ≈ 3.62 m³
Used mainly for firewood measurement in the US and Canada
Standardizes wood volume for sale and transport
Earth's Volume
The volume of Earth is approximately:
1.08321 × 10¹² km³
or
1,083,210,000,000 cubic kilometers
This value is based on Earth being roughly a sphere (though it's slightly flattened at the poles), with an average radius of about 6,371 kilometers. The formula used to calculate the volume of a sphere is:
V=34πr3
Substituting Earth's average radius:
V=34π(6,371)3≈1.08321×1012 km3
This immense volume gives Earth enough space to hold all of its oceans, atmosphere, and solid mass. It's a key figure in geophysics, helping scientists understand Earth's mass distribution, density, and structure.
