To find the width of the right rectangular prism, we can use the formula for the volume of a rectangular prism:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
Given:
- Volume = 1,000
- Height = 10
- Length = 20
We can plug in the values into the formula:
\[ 1,000 = 20 \times \text{width} \times 10 \]
Next, we can simplify the equation:
\[ 1,000 = 200 \times \text{width} \]
Divide both sides by 200:
\[ \text{width} = \frac{1,000}{200} = 5 \]
So, the width of the prism is 5.
