Arectangular block of copper metal weighs 1896 g. the dimensions of the block are 8.4cm by 5.5 cm by 4.6 cm. from this data, what is the density of copper?

The density of copper is 8.9 g/cm³.

V = lwh = 8.4 cm × 5.5 cm × 4.6 cm = 212 cm³

Density = mass/volume = 1896 g/212 cm³ = 8.9 g/cm³

Note: The answer can have only two significant figures because that is all you gave for the dimensions of the block.
