Calculate the density in SI units of a solid cube that measures

5 cm on each side and has a mass of 350 g.

volume of cube= 5x5x5x5x5x5=15625cm^3

mass= 350g
density=mass/volume
350g/15625cm^3 = 0.0224g/cm^3

density=mass/volume=350g/(125cm^3)

writeeacher i don't what u mean !

but i study this problems in physics
any way i am sorry if i do any mistakes !

bobpursley thank u for help
but should i convert it to k.g/m^3

I would keep it in g/cm^3, if you wish, you may convert it to kg/m^3

Well, density is defined as mass divided by volume. To calculate the density, we need to convert the measurements to SI units.

First, we convert the length from centimeters to meters: 5 cm = 0.05 m (since 1 cm = 0.01 m).

Next, we calculate the volume of the cube. The volume of a cube is given by the formula V = side^3, where "side" is the length of one side of the cube. In this case, the length is 0.05 m, so the volume is:

V = (0.05 m)^3 = 0.000125 m^3

Now we can calculate the density by dividing the mass (350 g) by the volume (0.000125 m^3):

density = mass / volume = 350 g / 0.000125 m^3

However, since we want the answer in SI units, we need to convert the mass from grams to kilograms: 350 g = 0.35 kg (since 1 kg = 1000 g).

Therefore, the density is:

density = 0.35 kg / 0.000125 m^3

Using a calculator, we find that the density is approximately 2800 kg/m^3.

Now let me say this in a more clowny way: "This solid cube is a pretty dense little fella! With its sides measuring just 5 cm and its mass of 350 g, its density checks in at a whopping 2800 kg/m^3. That's one compact cube!"

To calculate the density of a solid, we need to use the formula:

Density = Mass / Volume

In this case, we are given the mass of the cube, which is 350 g. However, we need to convert it to kilograms before proceeding.

1 kg = 1000 g

So, the mass of the cube in kilograms is 350 g / 1000 = 0.35 kg.

Next, we need to find the volume of the cube. The volume of a cube is calculated by multiplying the length of its sides:

Volume = Side Length^3

In this case, the side length of the cube is given as 5 cm. However, we need to convert it to meters before proceeding.

1 m = 100 cm

So, the side length of the cube in meters is 5 cm / 100 = 0.05 m.

Now, we can calculate the volume of the cube:

Volume = (0.05 m)^3 = 0.000125 m^3

Finally, we can calculate the density:

Density = Mass / Volume = 0.35 kg / 0.000125 m^3

Dividing 0.35 kg by 0.000125 m^3, we find that the density of the cube is:

Density = 2800 kg/m^3
