I did my homework and there are some bonus questions that we really never learned about in class, if we get them right it adds to the mark, it says find mass and volume and things, any help?
brysonlee said:The question is, A material has a density of 50kg/m cubed, and sides that measure 2m, 2m, and 5m, find the mass
other is
A material has a density of 6 kg/m cubed, and a mass of 22kg, find the volume,
For the second question would you multiple density and mass, or divide?
To calculate mass, you need to know the density and volume of an object. The formula for mass is mass = density x volume. You can find the density of a substance by dividing its mass by its volume.
Volume is a measure of the amount of space occupied by an object. To find the volume of a regular-shaped object, you can use a formula specific to its shape. For irregular-shaped objects, you can use the water displacement method by measuring the amount of water an object displaces when submerged in a graduated cylinder.
The most commonly used unit for mass is the gram (g). In some cases, kilograms (kg) or milligrams (mg) may also be used. In the scientific community, the standard unit for mass is the kilogram.
The most commonly used unit for volume is the liter (L). In some cases, cubic meters (m3) or milliliters (mL) may also be used. In the scientific community, the standard unit for volume is the cubic meter.
To convert between units of mass and volume, you need to know the density of the substance. You can use the formula density = mass/volume to convert between units. For example, if you have the mass of an object in grams and want to convert it to kilograms, you can divide the mass by 1000 to get the mass in kilograms.
