Question

calculating density
using the formula for density, where density = mass divided by volume (d=m/v), calculate the density of the objects in the table below.

object	mass	volume	density
wooden block
large glass marble	20 g	8.2 cm³

Explanation:

Step1: Identify the formula

The formula for density is \( d = \frac{m}{v} \), where \( d \) is density, \( m \) is mass, and \( v \) is volume.

Step2: Calculate density for Large Glass Marble

For the Large Glass Marble, mass \( m = 20 \, \text{g} \) (assuming the mass is 20 g as the image shows "20g") and volume \( v = 8.2 \, \text{cm}^3 \).
Using the formula \( d = \frac{m}{v} \), we substitute the values:
\( d = \frac{20}{8.2} \approx 2.44 \, \text{g/cm}^3 \)

(Note: For the Ping Pong Ball and Wooden Block, the mass values are missing in the provided table, so we can't calculate their densities without that information. Here we calculate the density for the Large Glass Marble as it has both mass and volume values.)

Answer:

The density of the Large Glass Marble is approximately \( 2.44 \, \text{g/cm}^3 \). (For Ping Pong Ball and Wooden Block, mass values are needed to calculate density.)
