Final answer:
The density of the metal block is calculated by dividing its mass, 780 g, by its volume, 60 cm³, resulting in a density of 13 g/cm³.
Step-by-step explanation:
To calculate the density of a block of metal, we need to find its mass and volume. The mass is given as 780 g. We can find the volume by multiplying the dimensions of the block, which are
Width: 2 cm
Height: 5 cm
Length: 6 cm
So, the volume (V) is 2 cm × 5 cm × 6 cm = 60 cm³. To find the density (D), we use the formula D = m/V. Substituting the known values, we get D = 780 g / 60 cm³, which simplifies to 13 g/cm³.
