To find the width of the right rectangular prism, we can use the formula for the volume of a rectangular prism:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
We know that:
- Volume = 1,000
- Length = 20
- Height = 10
- Width = ?
We can rearrange the formula to solve for width:
\[ \text{width} = \frac{\text{Volume}}{\text{length} \times \text{height}} \]
Substituting the known values:
\[ \text{width} = \frac{1000}{20 \times 10} \]
Calculating the denominator:
\[ 20 \times 10 = 200 \]
Now substituting back:
\[ \text{width} = \frac{1000}{200} = 5 \]
Therefore, the width of the prism is 5.
