4 Questions
What is the formula for calculating density?
The formula for calculating density is $ ho = rac{m}{V}$, where $ ho$ represents density, $m$ represents mass, and $V$ represents volume.
How can density be measured for regular solids?
Density can be measured for regular solids by dividing the mass of the solid by its volume.
What are some examples of regular solids?
Examples of regular solids include cubes and cuboids.
What is a eureka can and how is it used?
A eureka can, also known as a displacement can, is a beaker with a spout that can be used to measure the volume of irregular objects.
Study Notes
Density and Regular Solids
- The formula for calculating density is: density = mass / volume
- Density can be measured for regular solids by measuring the mass of the object using a balance and the volume by measuring the dimensions (length, width, and height) and applying the formula: volume = length × width × height
Examples of Regular Solids
- Cubes
- Rectangular prisms
- Spheres (although measuring the volume can be more complex in this case)
Eureka Can
- A eureka can is a sealed container filled with water, used to measure the volume of an object by displacement
- To use a eureka can, an object is submerged in the water, and the volume of water displaced (i.e., the volume of the object) is measured by reading the new water level on the side of the can
