Question

Billy is trying to figure out what type of wood to use for building a model boat. He has a block of wood with a volume of 8.0 cubic centimeters (cm) and a mass of 4.0 grams (g). What is the density of the block of wood in g/cmº to the nearest tenth? 0.5 2.0 4.0 32.0​

Answer 1

ρ = 0.5 g/cm³

Step-by-step explanation:

Step 1: Given data

Volume of the block of wood (V): 8.0 cm³

Mass of the block of wood (m): 4.0 g

Density of the block of wood (ρ): ?

Step 2: Calculate the density of the block of wood

The density of the block of wood is equal to its mass divided by its volume. The mathematical expression is:

ρ = m/V

ρ = 4.0 g/8.0 cm³

ρ = 0.5 g/cm³
