This is hard to calculate precisely, due to the fact that Earth's density increases towards the center. However, you make a simplified calculation, by assuming a uniform density. Just calculate the ratio of the volume (and therefore, of mass) of a sphere which has half the radius of the Earth, and calculate the gravitational attraction (once again, you only need a ratio, compared to the complete Earth) on that object.
Weight The force of gravity on an object is its weight. If we know the mass of the object, and the acceleration due to gravity we can calculate the weight of an object as follows weight= mass x acceleration due to gravity W=mg Units : newtons (because weight is a force) Example: Given an object on the surface of the earth Mass of the object=1 kg acceleration due to gravity on the surface of the earth is approximately 9.8m/s2 -->W=mg=1x9.8=9.8 newtons
You cannot use surface area to calculate density. Density is a calculation comparing TOTAL area and weight of an object. In short you must use the total volume of the object when calculating the density.
No, your weight is just the acceleration due to the Earth's gravity,
Given an object if contact with a surface, the limiting frictional force is directly proportional to the normal reaction to the weight of the object at its point of contact with the surface.

Weight is actually force in a fixed setting. In the context of a relatively large and uniform gravitational field (such as being on the surface of the planet), weight is the force along the line between the center of the gravitational field and the center of the object. That is, the weight of an object in such a gravitational field is the strength of that field multiplied by the mass of the object.
The weight of an object on the moon's surface is 16.3% of the same object's weight on the earth's surface.

You cannot. Ask yourself how much does a mile weigh, or a foot, kilometre etc.You need more information such as what material, the other dimensions and the density.
Object's massLocal gravitation field strength
balance your chemical reaction equation then calculate moles, then calculate weight.
Given an object if contact with a surface, the limiting frictional force is directly proportional to the normal reaction to the weight of the object at its point of contact with the surface.
