The problem states that an object has a density of $20 \, \text{g/cm}^3$ and a volume of $25 \, \text{cm}^3$. We need to find the mass of the object.

1. Problem Description

The problem states that an object has a density of $20 \, \text{g/cm}^3$ and a volume of $25 \, \text{cm}^3$. We need to find the mass of the object.

2. Solution Steps

We know that density is defined as mass per unit volume. The formula is:

$\text{Density} = \frac{\text{Mass}}{\text{Volume}}$

We are given the density and the volume, and we want to find the mass. We can rearrange the formula to solve for mass:

$\text{Mass} = \text{Density} \times \text{Volume}$

Now we can plug in the given values:

$\text{Mass} = 20 \, \text{g/cm}^3 \times 25 \, \text{cm}^3$

$\text{Mass} = 500 \, \text{g}$

3. Final Answer

The mass of the object is $500 \, \text{g}$.
