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.
The density of copper is 9.86g/cm square
Work out the mass of the solid copper cuboid in kg
10cm 3cm 5cm
