get a beaker or measuring cup of water and fill it to an even point and record it. then put the pen in the water and record new measurement of water. subtract the new measurement from the old one and you have the volume of the pen! :)

The Easiest way- fil a marked measuring cup with enough water to cover the pear. Note the measurement. now push the pear into the water. Note the larger measurement. Subtract smaller from larger. Difference is the volume of water the pear displaced, which is equal to the volume of the pear.
An acre is a constant unit of measurement - an acre of anything is equal to an acre of anything else.
Can't determine this without a third measurement.
1) Measure the height of water in a beaker or a bowl. (First Measurement) 2) Place the object in the water. 3) Measure the height of the water while the object is still in the water. (Second Measurement) 4) Subtract your first measurement from your second measurement.
Place a specific amount of water in your bottle. Record the volume. Place the rock in the bottle. Read and record the new volume of water. Subtract the first volume measurement from the measurement after you added the rock. The difference is the volume of the rock.
A measurement of how much water vapor is in the air at any particular place is called relative humidity. Relative humidity is measured with a psychrometer.
Use the water displacement method. You need a graduated cylinder and some water. Fill the graduated cylinder with enough water so that when you place the rock in the graduated cylinder it will cover the rock. Read the meniscus (the slightly curved line of the water) at eye level. Record your measurement of the water in the graduated cylinder (in mL). Place the rock in the graduated cylinder and record your new measurement of the water line, again at eye level. Subtract the original measurement from the new one to get the volume of the rock.
You can measure the temperature of ice water using a thermometer designed for lower temperatures. Place the thermometer in the ice water and wait until the reading stabilizes to get an accurate measurement.
Tablespoon is a common kitchen measurement of 15 ml of water.
The measurement of the grams of water in a kilogram of air is called specific humidity.
You can measure the temperature of water using a thermometer specifically designed for use in liquids. Place the thermometer in the water and wait for it to stabilize to get an accurate measurement. Submerge the thermometer deep enough to get an accurate reading.

should be (38/700)x100 then move the decimal place back
It is a measurement of the depth of water. One fathom = 6 feet.
