How do you find relative density?

Relative density can be calculated directly by measuring the density of a sample and dividing it by the (known) density of the reference substance. The density of the sample is simply its mass divided by its volume.

What is error in density of a cube?

We know , density is given by : Here , M is mass , V is volume of cube and a is edge of cube . Therefore , error in density of a cube is 5 % .

What is the mass of a cube?

The mass of a cube is calculated as its density times its volume. Volume can be calculated if one knows the length, width or height, as all three values are the same for a cube. Multiply these three values together to find the volume. Once the density and volume values are known, multiply them together.

What is the mass of a cube in grams?

The mass of a cube in grams is M=x^3+0.1x^4, where x is the length of one side in centimeters. If the length is increasing at a rate of 0.03 cm/hr, at what rate is the mass of the cube increasing when its length is 6 cm?

What is the density of a Rubik’s Cube?

Approximately 8.09 g/cm3

What is the height of a Rubik’s Cube?

5.6 centimetres

How many cubic units are in a Rubik’s Cube?

If we did not know that the volume was 24 cubic units, how could we figure it out? (Answer: We can count the number of cubes. Students may also share the volume formula, as being l x w x h.) Explain that you will present a short video to the class that explains the formula for volume using a Rubik’s cube.

Is density the same as volume?

Density and volume are scientific concepts pertaining to physical properties and characteristics of matter. Volume refers to the measurement of the amount of three-dimensional space occupied by an object. Density refers to the mass contained in a substance for a given volume.

How do you find the density of an object?

The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.

What is the density of an object?

An introduction to density Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter).
