You can find a rock's density in many different ways. That object has a high density and will not float on water.
Unless you can find both the mass and density of something you cannot find the density.
You need a scale to measure the weight and ways to submerge the block and measure the water to determine the volume.
Heat or cool the object and this will cause a density change.
Well you Find the density by doing Mass/Volume. If The objects density is less than 1 it will float
WAY 1: multiplying are and the depth of an object WAY 2: dividing weight by the density of an object

There are 2 ways to measure liquid density, by putting a set amount of the liquid in a container and measuring it with a 2 pan balance, and then subtracting the mass of the container or using a hydrometer to find the Specific Gravity.
To determine the density of a saline solution you can use a hydrometer.
here are 3 ways... 1) temperature going down 2) the salinity of the water 3) ice blocks...
Find the density of a material that has a mass of 2 kg and a volume of 5 m3.
The density is 0.4 kg/m
A typical density for black pepper is 550g/l. This really depends on what kind of pepper you are talking about. Here is a useful formula to find out the density of your method. D= M/V (Density equals Mass divided by Volume) You can find the Mass by weighing the pepper on a scale. You can figure out the approximate volume by measuring the pepper in different ways (depending on its size). Once you have the 2 results, you can divide the Mass of the pepper by the Volume of the pepper. The result would be the Density of the pepper.
Derive from measurements of length, breadth, height, radius, diameter etc. Measure the volume of displaced liquid when the object is submerged. If the object is of a material of known density (or specific gravity), weigh it and calculate volume from volume = mass/density.
here are 3 ways... 1) temperature going down 2) the salinity of the water 3) ice blocks...
There are two questions in your question. Question #1: How do you find the density ? Answer #1: Divide the mass by the volume. And this time, don't forget to include the units. Question #2: Find its volume ? Answer #2: 0.25
In order to calculate the density, we need to know the mass and the volume. You've given us the volume ... it's (4 x 2 x 2) = 16 cubic units. When you find out the mass in that volume, divide it by 16, and the quotient will be the density.
