Final answer:
The density of the block is 0.5 g/cm³.
Step-by-step explanation:
The density of a block can be calculated using the formula:
Density = Mass / Volume
Given that the block has dimensions of 5 cm x 2 cm x 10 cm and a mass of 50 grams, we can find its volume by multiplying the dimensions:
Volume = 5 cm x 2 cm x 10 cm = 100 cm³
Now we can calculate the density:
Density = Mass / Volume = 50 g / 100 cm³ = 0.5 g/cm³
