calculate the mass of cube which has a density of ,1000kg/m^3 and side of length 2m

(2m)^3 * 1000kg/m^3 = 8000kg

To calculate the mass of a cube, you need to know the density of the material and the volume of the cube. In this case, you have the density given as 1000 kg/m^3 and the side length given as 2m.

The volume of a cube can be calculated using the formula V = s^3, where "V" is the volume and "s" is the length of the side.

Plugging in the given side length of 2m into the formula, we have:

V = (2m)^3
V = 2m * 2m * 2m
V = 8m^3

Now that we have the volume, we can calculate the mass using the formula m = ρ * V, where "m" is the mass, "ρ" is the density, and "V" is the volume.

Plugging in the given density of 1000 kg/m^3 and the calculated volume of 8m^3 into the formula, we have:

m = 1000 kg/m^3 * 8m^3
m = 8000 kg

Therefore, the mass of the cube is 8000 kg.

To calculate the mass of a cube, you need to multiply the density of the material by the volume of the cube.

The volume of a cube is found by multiplying the length of one side by itself twice, or L^3. In this case, the length of the side is given as 2m, so the volume of the cube is:

Volume = (2m)^3 = 2m * 2m * 2m = 8m^3

Now, you can calculate the mass by multiplying the density (given as 1000 kg/m^3) by the volume:

Mass = Density * Volume
= 1000 kg/m^3 * 8m^3
= 8000 kg

Therefore, the mass of the cube is 8000 kg.
