What is the demensions of a cube with a density of 2.70 g mL and weighs 20.00 g?

it's 20.00/2.70 so it's 7.41 ml.
g/ml if you think as g divided by ml you get
20/?= 2.7 so
2.7 x ? =20 so
20 / 2.7=? = 7.41 (to 2 d.p.)
hope this makes sense.

Since density is mass divided by volume (D = m/V), we can rearrange the formula to solve for volume: V = m/D. In this case, the volume of the cube is V = 20.00 g / 2.70 g mL = 7.41 mL. Since a cube has equal sides, we can calculate the side length by taking the cube root of the volume: side length = (7.41 mL)^(1/3) ≈ 1.95 cm.

∙ 9y agoA density of 2.5 grams per cubic centimeter means a 20 gram cube would be 7.41 cubic centimeters. This indicates that each side of the cube would be 1.949 cm long.

If the mass of the cube 96g what is the density of the cube material?
To find the density of the cube material, divide the mass of the cube by its volume. You would first need to know the volume of the cube to calculate its density accurately. If the volume of the cube is 8cm³, then the density would be 96g/8cm³ = 12g/cm³.
Well every solid with the same dimensions have the same density?
No. There are many, many different kinds of solid, and they come in a variety of densities. Something like a brick is fairly heavy, but if it was made of wood, it would be a lot lighter and a lot less dense. There are a zillion other examples that could be cited.
If a cube is floating and half of it is in the water what is its density?
The density of the floating cube is equal to the density of the fluid it is floating in. This is because the cube is in equilibrium, meaning the weight of the cube is equal to the weight of the fluid it displaces. Therefore, its density is the same as the fluid's density.
What is the density of a 60g cube?
Cannot be answered without knowing the size of the cube!If the cube were 1 cm on a side the density would be 60.If the cube were 10 cm on a side the density would be 0.06...We cannot determine the answer because we are not given the volume.Density= mass/volumeVolume of a cube=L3 ; where L = side length
How much does aluminum metal weigh?

What can only be measured in 3 demensions?
Cube.
What can the demensions of a cube be with 60 cm3?
If it's a cube it would be 3.914867 cm on each side.
What is the density of a plastic cube 1 cm long if it weighs 0.8 grams?
density = mass / volume volume of cube = 1cm x 1cm x 1cm = 1cm3 density = 0.8g / 1cm3 = 0.8g/cm3
A shape having the same demensions of lengthheightand weight?
"Weight", do you mean 'width'? If you do then a cube is the answer.
How do you find the density of a cube of butter that weighs 0.250 lb and has a volume of 130.3 mL?
To find the density of the butter, you first convert the weight from pounds to grams (1 lb = 453.592 g). Then, convert the volume from milliliters to cubic centimeters (1 mL = 1 cm^3). Finally, divide the mass by the volume to calculate the density in g/cm^3.
What it the density of a cube?
The density of a cube is calculated by dividing its mass by its volume. The formula to calculate density is: Density = Mass/Volume. The density of a cube will depend on the material it is made of.
If the mass of the cube 96g what is the density of the cube material?
To find the density of the cube material, divide the mass of the cube by its volume. You would first need to know the volume of the cube to calculate its density accurately. If the volume of the cube is 8cm³, then the density would be 96g/8cm³ = 12g/cm³.
What is the relative density plastic cube?
The relative density of a plastic cube is the ratio of the density of the plastic cube to the density of water. To calculate it, you would divide the density of the plastic cube by the density of water (usually 1 g/cm^3). If the relative density is less than 1, the cube will float in water, and if it's greater than 1, the cube will sink.
There's a green cube a blue cube and red cube and they weigh a total 36 grams altogether the green cube is 3 times heavier than the blue cube and the red cube is 5 times heavier than the blue cube.?
blue cube weighs x grams green cube weighs 3x grams red cube weighs 5x grams total weight = 9x grams = 36 grams x = 4 grams blue weighs 4g, green weighs 12g, red weighs 20g
Would the density of a cube change if the cube was cut into pieces?
No. Each piece of the cube would have the same density.
How much does 1 cube of heavy oil weigh?
The weight of 1 cube of heavy oil can vary depending on its density, but typically, a cubic foot of heavy oil weighs around 53 to 55 pounds.
