Best Answer

Refer to the definition of density: density = mass / volume. Also, each substance has its characteristic density, independent of its size. A pound of cement will have the same density as a ton of cement. And cement is more dense than rice, regardless of how big a chunk of each you take.

If 2 pounds of rice cost 5, 1 pound will cost 2.50 or 2 1/2.

The mass of one grain of rice is 25 milligram or .025 grams. There are about 29,000 rice grains in approximately one pound of long-grain white rice.

Extrapolating from the answer to how may grains in a pound of rice, 29,000, (elsewhere in Answers.com) we get something like 64,000 grains in a kilogram (@ 2.2 lbs / kg). This could vary based on the kind of rice.

It's not a lot of rice. Are you asking how it would cost? How much it is in ounces? How big of container to put it in? You need to be more specific.

Only once. When it has been cut down it does not sprout up, and grow grain again. You need to get a grain of rice seed and plant it, to get more rice. You can only harvest the crop once.

It depends if the rice is cooked or uncooked, as cooked rice will contain a lot of water and be more dense than uncooked rice. A pound of uncooked rice will yield about 3 times as many cups once it has been cooked than before it was cooked, but will also weigh more than three pounds. A cup of pure water (8 fluid ounces) weighs about 8.34+ ounces (weight), so 2 cups of water would weigh about 16.69 ounces or 1.043 pounds. Which means a pound of water yields 1.918 cups. (at 4 degrees Celsius) The density of water is 1,000 kilograms per cubic meter. The density of rice (hulled) is approximately 753 kilograms per cubic meter. So a pound of uncooked rice, being less dense than water, should yield approximately 2.55 cups. Once cooked that same pound of rice (at a ratio of 2 cups water to one cup rice) would weigh almost 3.66 pounds. Assuming no water is lost during cooking. Assuming my math is correct, it may not be. It is not possible to accurately calculate the number of cups this will yield - but it is likely to be about 6 cups or more. One needs to cook a pound of rice and measure the volume.

You can get twenty pounds of long grain white rice from Walmart for $9.98. That works out to just shy of 0.50Â¢ a pound, and nine pounds of arborio rice for $23.71 which is $2.63 a pound.
