The SI (Systeme Internationale or 'Metric') unit of Mass is the Kilogram
A standard bucket (c. 5 gallons) of water would have a mass of approximately 25Kg, so the Kilogram would be scientifically correct, as well as scale-appropriate.
Note that the Kilogram is not a unit of Weight - the Metric unit of weight is the Newton, N and represents the force exerted by the mass due to the force of gravity.
That is, even on the moon, the bucket would still have a Mass of 25Kg (No, really!), but its Weight would be drastically reduced due to the greatly reduced gravity.
Gallons
I'm not so sure. I hope you find it though.
You do not need fancy lab equipment.Basically you need to determine two pieces of information1) The mass of the "irregular" shape (use a scale)2) The volume of the shape (use water displacement in a bucket/tub to find volume)Take the mass / volume and you have density.
Find the mass of a known volume of the liquid and use the formula mass/volume to find the density.
A metric ruler would be the best bet. Simply measure the length, the width and the height of the box and multiple all three measurements together to find the volume of the box in the unit that you measured the boxes in, cubed.
Depends how much there is, most likely ml, but if there is a large quantity probably L.
Grams. Obviously.
you fill a 10 liter bucket full, you lower the horseshoe in and u mesuare the amount of water that got out of the bucket
The volume is measured in litres. 1 cubic decimetre (dm³) is 1 litre.
Assuming sides of your bucket are straight, then it is the height of the bucket multiplied by the area of the base.The volume of a bucket depends on the size of the bucket. Measure the inside width (diameter) of the bucket and find the radius of the bucket by dividing the diameter by 2. If the sides of the bucket slope, measure the diameter at the mid-point of the side. The volume of the bucket is pi (approximately 3.14) times the square of the radius times the inside height of the bucket. For example, if a bucket is 12 inches across and 15 inches high, the volume is 3.14 x 6 inches x 6 inches x 15 inches = 1696 cubic inches
A pipe has the shape of a cylinder; just use the formula for the volume of a cylinder. In metric units, you have the advantage that the units are consistent. For example, if the radius and height of the cylinder are measured in decimeters, the volume will be in cubic decimeters (= liters).
The metric system is more exact than the customary system.The unit meter is used to find length;millimeter is used to find volume.
In general it is very difficult. The displacement method, often given as the answer does not always work. The displacement method will work only if the object is reasonably small and you can find a liquid in which it is not soluble and in which it will sink. For small objects, pour some liquid into a calibrated measuring jar and read off the volume. Then you submerge the object and read off the new volume. The difference between the two measures is the volume of the object. For larger objects, it is easier to use two containers: for example a bucket placed in a basin. Completely fill the bucket. Very gently lower the object into the liquid in the bucket. Then carefully remove the bucket and measure the liquid that overflowed from the bucket into the basin. This will equal the volume of the object.
How can you?? If u dont know the width or the volume
Something to determine volume (like a bucket of water or a ruler), and a balance to determine mass. Divide the mass of the block by its volume to find the density of the block.
Liter is a unit of volume equal to 0.001 cubic meters. Metric ton (tonne) is a unit of mass, equal to 1000 kilograms. The only time you can find mass from volume, is if you have a specific substance of known density. For example, water has a density of 1 kg/liter =0.001 (metric ton / liter), so if you had 500 liters of water, then: 500 L * 0.001 (metric ton/L) = 0.5 metric tons
For a stone or a pebble the best method is to use a graduated cylinder and the displacement method. Fill the jar with water to a level so that the pebble can be completely submerged. Read of the volume. Then insert the stone or pebble into the cylinder and read off the new volume. The difference between the two will be the required volume. However, for a rock the equipment needs to be scaled up and graduated cylinders don't usually come that big. So you will need a bucket or something in which the rock can fit and a tray or large enough container to catch the spill from the bucket (see next paragraph). Put the bucket in the tray. Fill the bucket with water - full to the top. Then very gently lower the stone into the bucket, catching all the spilling water in the tray. Measure the water in the tray using whatever measuring equipment you can get hold of. That is the volume of the rock.
The answer to this question depends on the density of the two given substances. For the same volume a more dense substance will have more mass and will weigh more. Here, if we take buckets of same volume in both cases then the water bucket will be heavier as water is more dense than apples. Also water occupies the entire volume of the bucket while apples cant use up the entire volume of the bucket as they have fixed shape and spaces remain between them. If two buckets of different volumes are taken then easiest process would be to actually weigh the buckets to find the heavier one. Here, apples considered are the ones grown on apple plants and eaten. For any other substance cast in of shape of apples it's density has to be considered.
