Block being a box: Height * Length * Depth = Volume Giving the three dimensions available.
To calculate the volume of a block in cubic centimeters, you need to multiply the length, width, and height of the block in centimeters. The formula for volume is V = l x w x h, where V is the volume, l is the length, w is the width, and h is the height of the block.
Weigh the blockcalculate the volume of the block. This is done by measuring the length, height, and width of the block if it is rectangular. If it is some other shape then other mathematical formula apply. If it is an irregular shape for which no formula exists then you can estimate the volume by incremental methods or by displacement.divide weight by volume.
To calculate the density of the block of wood, you would divide its mass (in grams) by its volume (in milliliters). The formula for density is: Density = Mass / Volume. Plug in the values for mass and volume to find the density of the block in g/mL.
The blocks are of volume 1, 10, 100, 1000 cubic units.
The answer depends on what information you have been provided with. If you have only the linear dimensions then it is: Length * Breadth * Height
If it is a cubical block, the volume is simply length x height x width.
it is easy. You use Mass divided by Volume. You can Remember it by a heart. The top is a M and the bottom is a V. Mass divided by volume. <3
A graduated cylinder or volumetric flask could be used to measure the displacement of water when the wood block is submerged in it. By measuring the volume of water displaced, you can determine the volume of the wood block. A balance can then be used to measure the mass of the wood block, allowing you to calculate its density.
You cannot calculate volume of surface area. If you meant 20m3, then the volume would be 20,000 litres.
You will need the mass and volume of the block. To find mass, use an electronic balance. To find volume, use length x breadth x height. For irregular solid, use the water displacement method. The density is mass divided by volume.
IF you knew the volume of the block and the density of the material it was made of you could calculate it mass (mass = density * volume) but it is normal to measure the mass of something using a mass balance.
