A wooden block has a mass of 20 g and dimensions of 5 cm x 1 cm x 1 cm.
marta [7]

Answer:

V = 5 cm³

ρ = 4 g/cm³

Explanation:

Step 1: Calculate the volume (V)

We have a wooden cuboid of dimensions 5 cm × 1 cm × 1 cm. We can calculate its volume using the following expression.

V = 5 cm × 1 cm × 1 cm

V = 5 cm³

Step 2: Calculate the density (ρ)

The density is equal to the mass divided by the volume.

ρ = m / V

ρ = 20 g / 5 cm³

ρ = 4 g/cm³
