The answer will depend on what characteristic of the object is being measured: its mass, volume, surface area, colour, density etc.
Micrometers and vernier calipers
A torsion balance, a.k.a. Cavendish balance.
All you need is a scale. you should use a scale that measures in grams.
The body temperature is measured by a thermometer, the instrument to measure heat contents of objects is called a calorimeter. Don't confuse heat with temperature.
graduated cylindergraduated cylinderSubmerge your solid in a liquid the liquid volume displaced is equal to your irregular solid volume.
If you have a ruler then you could measure the length width and height and then multiply them together. (LWH is the formula)
L x W x H Lenght x Width x Hieght
Density = Mass / Volume. There is not an instrument that will measure both so you will need to measure them separately and calculate the density.
This instrument is a balance.
A tiltmeter measures changes in the tilt of the earth. :)A tiltmeter is an instrument that measures changes in the tilt of the earth. :)
A ruler no a better way is by dropping the cube in a liquid containg beaker displaced liquid will give you the volume
Any measure of length such as a ruler, yard stick, meter stick, tape measure, etc.
