The density of the object is 9 g/cm^3.
1.25 Volume should be expressed in volumetric units. If you mean 3.20cm3, then since density is mass per unit volume, in this case (4gm)/3.2cm3)=1.25gm/cm3.
To find the density, first calculate the volume of the block by multiplying the three dimensions (12cm x 8cm x 9cm = 864cm³). Then, divide the mass (75g) by the volume to find the density. So, the density of the wood block is 75g / 864cm³ ≈ 0.09 g/cm³.
Nothing really except that the two are connected in the scientific equation that states that "the density of a substance (in grams per cc) is found by dividing its mass (in grams) by its volume (in ccs). So a block of a substance measuring 12cm by 10cm by 5cm with a mass of 3 kilograms would have a density of 3000grams divided by 12 x 10 x 5 ccs which is 3000gms/600ccs = 5gms per cc. So each cubic centimetre would have a mass of 5 grams.
A 1dm pen is longer than a 12cm pencil. 1dm is equivalent to 10cm, so a 1dm pen would be 2cm longer than a 12cm pencil.
To find the frequency of a wave, you can use the equation: speed = frequency x wavelength. The speed of light is approximately 3 x 10^8 m/s. Convert 12cm to meters (0.12m) and plug in the values to solve for frequency: frequency = speed/wavelength = (3 x 10^8 m/s) / 0.12m ≈ 2.5 x 10^9 Hz.
3 grams per cubic centimeter :D
The question, as presented, is total nonsense since volume cannot be measured i cm. A centimetre is a measure of distance, not volume. The appropriate measure for volume is cubic centimetres or cc. Density = Mass/Volume = 36 g/12 cc = 3 grams per cc.
The volume is 12cm because 2 times 3 times 2 is equivalent to 12.
Density = Mass/Volume = 850/(9*7*12) = 1.1243 grams per cm3
1.25 Volume should be expressed in volumetric units. If you mean 3.20cm3, then since density is mass per unit volume, in this case (4gm)/3.2cm3)=1.25gm/cm3.
The equation for the density of an object with known mass m and volume V is D=m/V.You are given the mass to be 750g.To figure out the volume of the block of wood, simply multipy all of the dimensions. The volume of a right prism (e.g. a block of wood) is V=length*width*height, so the volume for the block of wood is 12cm*8cm*9cm=864cm3.Now you know both your mass and your volume, so you can calculate the density:D=m/VD=(750g) / (864cm3)D is roughly equal to 0.86806g/cm3.
To calculate the volume, multiply the length x width x height. volume = 12cm x 6cm x 4cm = 288cm3
It is done by: 12*6*4 = 288 cubic cm
12cm x6cmx4cm=288cubic centimeters
To find the density, first calculate the volume of the block by multiplying the three dimensions (12cm x 8cm x 9cm = 864cm³). Then, divide the mass (75g) by the volume to find the density. So, the density of the wood block is 75g / 864cm³ ≈ 0.09 g/cm³.
They are not compatible - cm is a measure of length, ml is a measure of volume.
10cm x 7cm x 12cm =840 square cm3
