Typically, one would use a tape measure or ruler and find the dimensions of the object. The dimensions are reported in length x width x height.
the perimeter is the distance around an object you add up the sides unless it is an odd shape than you could use a string and then measure that
The easiest way is to use Archimedes principle ! Immerse the object in a container of water that is full to the brim - then collect the displaced over-spill, and measure it.
A beaker. Simply fill the beaker with a known quantity of liquid. Drop the object into the beaker, and measure the difference in the fluid levels.
To measure the area of an arbitrary two dimensional shape you will use a planimeter. To measure an area you could also just use a simple ruler depending on how big the area is.
if your question is explain how to use a ruler to measure to the nearest inch the answer would be...you have to see what inch is the object your measuring to closest to
One method is to use the water displacement technique. Submerge the object in a graduated cylinder or container partially filled with water, then measure the increase in water volume. This increase in volume equals the volume of the irregular object.
Use a graduated cylinder to precisely measure volume
You could use a ruler or a measuring tape to measure the length of an object. Both tools have markings that allow you to accurately determine the distance from one point to another.
When the object is larger than the ruler.
Typically, one would use a tape measure or ruler and find the dimensions of the object. The dimensions are reported in length x width x height.
You can use trigonometry to measure the height of an object that is too far away to directly measure the distance to. By measuring the angle of elevation from your position to the top of the object and knowing your distance from the object, you can use trigonometric functions to calculate the height.
To measure a foot length you could use a ruler, a yard stick, a tape measure, or any object that you knew was precisely one foot long on a side or edge.
A scale.
[object Object]
Use a ruler.
You could use a water displacement method, where you submerge the object in a graduated cylinder filled with water and measure the change in water volume. Alternatively, you could use a 3D scanner to create a digital model of the object and calculate the volume from the model.
