length times width times height or l x w x h
There is no "unit of measurement for a plastic block". The SI has units of length, area, volume, mass, tensile strength, etc.; please clarify what aspect of the plastic block you want to measure.
A ruler. Measure the length, width, and height. Then multiply the three of the to get the volume. Equation: V=LxWxH V=Volume L=Length W=Width H=Heigtht x=multiply Example: A block of wood has a length of 4, a height of 2, and a width of 3. What is the volume? 4x2x3=24
It depends on the volume of the block and the mass. The equation D=M/V Density=mass/volume The answered is displayed as (answer) grams/(the units in which you measured the volume) I hope this helps.
What is the density of a plastic block with a mass of 2.0 grams and a volume of 2.5cm3?
You need a scale to measure the weight and ways to submerge the block and measure the water to determine the volume.
you can measure the mass by putting it on a balance and measure really quickly. the volume you can estimate an approximate answer by putting it in water and measuring its displacement.
The SI unit for volume is cubic metres (m3).Litres (L) is also sometimes used.
Cubic centimeter.
Easiest way is to fill a kitchen measuring container to the top with water. Now slowly immerse the plastic block into the water and collect every drop of water that overflows when you do this. Having collected this overflow, measure its quantity by pouring every drop of it into a measuring container. This collected overflow represents precisely the volume of the plastic block.The number of millilitre (ml) you collected will be the number of Cubic Centimetres of volume of the plastic block. Remember always, that ml = cc . In other words 1 millilitre of fluid occupies exactly 1 cubic centimetre of volume. Now you see why the Metric system is so commonly used , and is so simple to use.A ruler could be used to measure the dimensions- if the plastic block were a regular straight sided object whose volume was easy to calculate. The calculation would be simple for a cube or rectangular prism, but could be quite complicated for other shapes.Archimedes came up with the best solution when he invented the Eureka jar. This is a vessel with carefully positioned overflow tube which allows any displaced water from the fully filled vessel to be collected.If you fill a Eureka jar to the point where it is about to overflow, then place the plastic block in in the jar (if it floats one would need to press it under the water with a piece if thin wire (whose volume is negligible) and collect all the water that overflows in a measuring cylinder - that is assuming the object is small and not the size of a family car. The volume of water collected will equal the volume of the plastic block.
Length x Breadth x Height
It is not possible to answer the question. The volume of a rectangular block requires the measure of three lengths - not 2 as given in the question.
The equation for the volume of a rectangular prism (such as a block of ice) is height times width times depth. That would make the volume of this block of ice is 9 meters cubed.
