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 .
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.
you weigh the block on a balance get its mass if it is a regular shape block so the volume should be length * weadth * breadth (side * side * side) the density = mass / volume
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.
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.
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
The answer depends on what information you have been provided with. If you have only the linear dimensions then it is: Length * Breadth * Height
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)
The answer depends on what information about the block you do have. If you have its length, breadth and height, then the area is 2*(L*B + B*H + H*L) square units.
The Density of aluminium is always 2.7g/cm3. To find the density you have to calculate the mass, lenght, breadth and height. Afterwards you have to find the volume (lxbxh).After you find the volume you have to use the formula: = mass/volume.density
You need three linear measures (length, breadth and height) to calculate a volume.
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)
