What is the length of a rectangle that has a width of 8 centimeters and an area of 256 square centimeters?
If the area of a rectangle is found by measuring the length times the width, then if you know the area is 256 and the width is 8, you find the length by dividing 256 by 8 which would give you a length of 32 centimeters.
What instrument is used to measure the length of a matchbox?
A micrometer is typically used to measure the length of a matchbox. Micrometers are precise measuring instruments that can accurately measure small dimensions with a high level of accuracy. By using the thimble and the spindle of the micrometer, the length of the matchbox can be measured to the nearest thousandth of an inch or hundredth of a millimeter.
How do you calculate the mass given diameter and length?
You cannot. Diameter and length can, for some particular shapes, give you the volume. But that will not give you the mass unless you know the density of the substance.
Which of the following represent the same level of precision Check all that apply.?
Not enough information has been provided to give a precise answer.
How can you calculate the volume of a stone when its in water?
you subtract the weight of the water from the weight of the measuring cylinder and you get the volume of the stone
What instruments give the greatest precise measurement?
measuring tape
What is a measuring device or tool for mass?
A scale is a measuring device commonly used to measure mass. It can be digital or mechanical and is designed to give an accurate reading of an object's weight in units such as grams or kilograms.
What are the device of measurement?
measuring devices are really important so that you can give accurate information regarding measurements.
How to measuer Precision?
The precision of anything can be measured using a suitably accurate measuring device appropriate to the task. For instance a one metre measuring rod may be accurately measured as being 995mm by a suitably accurate measuring device. The rod will always give a precise measurement, if external infuences do not change, e.g. temperature. It will never be one meter, but will constantly be 995mm. This is precision. If what you are trying to measure is one metre, to an accuracy of 0.01%, then this rod does not meet your needs. Precision is also known as repeatability. Accuracy is the closeness of the indication to the true (real) result.
What is measured in Milimeter?
Millimetres are normally used for measuring small things such as insects. But they are also used to give precise measurements for large things such as kitchen appliances.
What is the length of a rectangle that has a width of 8 centimeters and an area of 256 square centimeters?
If the area of a rectangle is found by measuring the length times the width, then if you know the area is 256 and the width is 8, you find the length by dividing 256 by 8 which would give you a length of 32 centimeters.
How does one measure the heat given off by a pepper What are the units called?
A somewhat imprecise method of measuring a pepper's heat is via the "scoville unit", a more precise method of measuring heat is via HPCL and will give the concentration of the active heat producing compounds called capsaicins.
What tool is used to find out the length of something with meters?
A steel measuring tape will give an accuracy to within a millimeter. A laser 'gun' can also be used, but one that is more accurate than a normal measuring tape is rather expensive.

Which set of tools will provide the most precise measurements for calculating the density of an irregulary shaped rock?
It depends on the size and mass of the rock. For a "normal" rock (as opposed to merely a stone) I suggest a crane with some means for measuring the rock's mass. A number of pulleys, each with a weighing machine should do the trick. Alternatively, you could use a weighbridge, if there is one in the vicinity. To obtain its volume, you probably need a 3-d laser-profiling device. That should give the most precise measurement of its volume.
Is a teaspoon customary or metric?
It equals 15 mils. But if you are measuring a dry ingredient by tablespoons it is not possible to give a 'weight' you should use, since that will vary according to what you are measuring (since a tablespoon is a measure of volume and grams is a measure of weight). For example a tablespoon of sugar will weigh less than a tablespoon of lead will.
Can you give me examples of measuring?
thermometer
