The density of copper is 9.86g/cm square

Work out the mass of the solid copper cuboid in kg
10cm 3cm 5cm

To find the mass of the copper cuboid, we need to use the formula:

Mass = Density x Volume

The volume of the cuboid can be found by multiplying the length, width, and height:

Volume = Length x Width x Height

Volume = 10cm x 3cm x 5cm = 150 cm³

Now, we can substitute the values into the formula:

Mass = 9.86 g/cm³ x 150 cm³

The volume is in cm³ and the density is in g/cm³, so the mass will be in grams (g). To convert it to kilograms (kg), we need to divide by 1000:

Mass = (9.86 g/cm³ x 150 cm³) / 1000

Mass = 1479 g / 1000

Mass = 1.479 kg

Therefore, the mass of the solid copper cuboid is 1.479 kg.
