what is the unit for the mass
density = mass over volume
volume= length*height*width
check the units whether you need to convert or no and then complete it
If it is a cubical block, the volume is simply length x height x width.
length x width x height
If its a cuboid, volume = length * breadth * height .
V = length x width x height
Not enough information. A room normally has the shape of a rectangular block; if that is the case, you can calculate its volume by multiplying length x width x height.
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.
Density (kg/m3) = mass (kg)/Volume (m3) So to find the density of the wooden block, the triple beam balanced is used to calculate the mass and the metre rule is used to measure the height, length and width of the wooden block. Then the volume is calculated by multiplying the thee distances obtained from the ruler. Finally the density is calculated using the equation: Density (kg/m3) = mass (kg)/Volume (m3)
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.
Density is mass/volume. For a rectangular block, the volume is [width x height x length].Assuming you meant 10 cm for width, instead of 10g, then:Volume = (10 cm)*(2 cm)*(10 cm) = 200 cm3Density = mass/volume = (200 g)/(200 cm3) = 1 g/cm3
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.
Block being a box: Height * Length * Depth = Volume Giving the three dimensions available.
If it is a cubical block, the volume is simply length x height x width.
the density would be 13.5. the density would be 13.5.
To find the density of a block, you would need a scale to measure its mass and a ruler or caliper to measure its dimensions (length, width, and height). Once you have these measurements, you can use the formula Density = Mass/Volume to calculate the density of the block.
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.
To find the density of an object, the formula is Density=Mass/volume so to be able to calculate the blocks density you need to know the volume of the object (volume=length* width*height)
The answer depends on what information you have been provided with. If you have only the linear dimensions then it is: Length * Breadth * Height
