To find the density of and object we must first know both its mass and its volume, then density can be calculated using the formula d=m/v.
In this case we do not know the volume but we do know the object's length, bredth and height. The volume can then be be calculated using the formula V= l*b*h
This gives a volume of 18 cm3.
Using the following information we can now calculate the object's density.
m=36
v=18
36/18=2
Density= 2 g/cm3 (grams per cubic centimetre)
Mass
What is the density of a rectangular object with the height of 5 cm the length of 10 cm, the width of 2 cm and the mass of 50 g
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
You can't. You'd need to know density and height of rod.
density = mass/volume mass= 425g volume=length*width*height = 1.6cm*2.5cm*8.0cm = 32 cm3 density = 425g / 32cm3 density = 13.28125 g/cm3
To calculate density with only length, width, and height, you need to also know the mass of the object. Density is calculated by dividing the mass of an object by its volume, which can be found by multiplying length, width, and height. The formula for density is: density = mass / (length x width x height).
You can calculate the volume by multiplying height, width, and mass. Then, divide the mass by the density to find the volume. Finally, calculate the length by dividing the volume by the height and width.
Density = mass ÷ volume, which can also be written as Density = Mass ÷ (length x width x height). Height is your thickness, so isolating the variable gets you Height = Mass ÷ Length ÷ Width ÷ Density.
Length, width and height will give you volume. You still cannot compute the density unless you know the mass.
Mass
What is the density of a rectangular object with the height of 5 cm the length of 10 cm, the width of 2 cm and the mass of 50 g
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
Indeed there is a relationship. Density is equal to the mass divided by the volume (height times width times length). So, height is equal to mass divided by (height times length times width) or H= M/(HLW)
Volume = Length x Width x Height, for a cube and Density = Mass / Volume.
You can't. You'd need to know density and height of rod.
density = mass/volume mass= 425g volume=length*width*height = 1.6cm*2.5cm*8.0cm = 32 cm3 density = 425g / 32cm3 density = 13.28125 g/cm3
A rectangular prism has a volume that can be found by multiplying the object's length width and height. To obtain the mass one must also know the density of the object and multiply that by the volume.
