width x length x height
ANSWER:If the cement block has holes in it and isn't solid like a brick, you can use the water displacement method.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.
To measure the density of a block, you would first measure the block's mass using a scale, then measure its volume by taking its length, width, and height measurements. Divide the mass by the volume to calculate the density of the block.
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.
To find the density of a block, calculate the block's mass and volume. Then, divide the mass by the volume to get the density. The formula is density = mass/volume.
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.
If the density of the block is less than the density of water, then the block will float. Density of water is close to 1 gram per cubic centimeter. So measure the block and calculate its volume (Length x Width x Height). Use a scale to find the block's mass. Then divide mass/volume to calculate density. If you've measured in grams and centimeters, then the units will be g/cm³, then compare this to 1 g/cm³.
To calculate the density of a block, you would need to know its mass and volume. Density is calculated by dividing the mass of the block by its volume: Density = mass/volume. The resulting value will be in units such as grams per cubic centimeter (g/cm3) for solid blocks.
