just normal hard rock.

Most rocks have a specific gravity of between 2.5 and 2.9. Therefore a cubic meter of rock would weigh 2,500 to 2,900 kg. Of course there are exceptions, but 90% of the rocks found on the earth's surface would be in that SG range.
Here are the SG's of some common rocks:
sandstone: 2.5
granite: 2.7
limestone: 2.65
slate: 2.8
rhyolite: 2.7
basalt: 3.0
Of course there are rocks lighter and heavier than that, but you said "normal."

1 cubic metre = 1 m * 1 m * 1 m = 100 cm * 100 cm * 100 cm = 1,000,000 cc 1 cc of water weighs 1 gm so, 1 cubic metre water weighs 1,000,000 gm = 1,000 kg = 1 metric tonne

There's no such thing as 'normal' rock, there are loads of different types. Some types, such as pumice, are less dense than water (less than 1000 kg/m^3), and float. Some rocks, with high metal content, can be 8 or so times that.

No such thing as "normal hard rock"... Granite is dense and heavy while Limestone is lighter. Of course one answer could be to take the weight of the earth (mostly rock) and consider that an "average" rock and divide that by its volume. Those stats are easily looked up on the net.

MXB is close. Take the MASS of the earth and divide it by the volume (4/3)pi*r^3 with r=~4000 miles. Weight has to do with mass in a gravitational field. You could compute the weight of the earth on Jupiter or the sun, for example, but the weight of the earth in its own gravitational field is a meaningless concept.

Lots of things can help lose weight, a good nights sleep, exercise, not eating too much junk food, eating sensible amounts of fruit and vegetables, and yes green tea may help do it's bit by assisting your bowel movement. Get more information here:

Not all fruits are equal. Some fruits are high in carbohydrates and they will not help you to lose weight.
The low carbohydrate fruits tend to be fresh (unsweetened) berries, There are many fruits that can help your weight loss progress. Learn here:

granite weighs 2.66 times the weight of water.
