Since a liquid has no definite shape or form, it needs to be held in a container.
Density = mass / volume
So you need a container with graduated markings so that you can measure the volume of the liquid, also, you need the mass of the empty container. You will need to subtract the mass of the empty container from the total mass (liquid and container) to find the mass of the liquid.

To find the density of a rectangular solid, you need to measure its mass and volume. The density is calculated by dividing the mass of the solid by its volume: Density = mass / volume. Make sure to use consistent unit measurements for accurate results.
liquid has no definite shape but an irregular solid has a definite shape.

Just by using Archimedes Principle
To find the density of a rectangular solid, first measure the mass of the solid using the balance scale. Then, measure the dimensions (length, width, and height) of the solid using a metric ruler. Calculate the volume of the solid by multiplying the three dimensions. Finally, divide the mass by the volume to find the density of the rectangular solid.
mass/volume=density
To find the density of the solid, you can use the formula: density = mass/volume. In this case, the mass of the solid is 55.234 grams and the volume displaced is the difference in the water levels, which is 25.7mL - 18.6mL = 7.1mL. Therefore, the density of the solid is 55.234g / 7.1mL = 7.78 g/mL.
Examples of rectangular solids include shoeboxes, shipping boxes, and refrigerators. These objects have six faces that are rectangles, and all their edges are right angles.
Density is defined as mass divided by volume. The volume of a rectangular solid is given by length × width × height, which in this case is 3 cm × 2 cm × 1 cm = 6 cm³. Therefore, the density of the solid is 12 g / 6 cm³ = 2 g/cm³.
