the density of copper is 9.86 g/cm^3 work out the mass of the copper cuboid in kg
It'd be nice to know the volume of the cuboid. In any case,
mass = density * volume
To work out the mass of the copper cuboid in kilograms, you will need to know the volume of the cuboid and use the density of copper.
To find the volume of the cuboid, you will need to know its dimensions (length, width, and height). Let's assume the length (L) of the copper cuboid is 10 cm, the width (W) is 5 cm, and the height (H) is 2 cm.
The volume (V) of a cuboid can be calculated using the formula: V = L x W x H.
In this case, V = 10 cm x 5 cm x 2 cm = 100 cm^3.
Now, you have the volume of the cuboid as 100 cm^3 and the density of copper as 9.86 g/cm^3.
To find the mass (M), you can use the formula: M = Density x Volume.
In this case, M = 9.86 g/cm^3 x 100 cm^3.
Now, you need to convert the mass into kilograms. Since 1 kg = 1000 g, you can divide the mass by 1000:
Mass in kg = (9.86 g/cm^3 x 100 cm^3) / 1000 = 0.986 kg.
Hence, the mass of the copper cuboid is 0.986 kg.
To work out the mass of the copper cuboid in kilograms, you'll need both the density and the volume of the copper cuboid. Since the density is given as 9.86 g/cm^3, and the mass is usually measured in kilograms, we'll need to convert the density unit from g/cm^3 to kg/cm^3.
To convert from grams to kilograms, you divide the value by 1000. Therefore, the conversion factor is 1 g = 0.001 kg.
Now, let's move on to calculating the mass using the formula:
Mass = Density x Volume
However, since the dimensions of the copper cuboid are not provided, we cannot directly calculate the volume. If you have the dimensions (length, width, and height) of the cuboid, please provide them, and I'll be able to guide you in calculating the mass.
