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 rearrange the formula to solve for width:
\[ \text{width} = \frac{\text{Volume}}{\text{length} \times \text{height}} \]
Now plug in the values:
\[ \text{width} = \frac{1000}{20 \times 10} \]
Calculate \(20 \times 10\):
\[ 20 \times 10 = 200 \]
Now substitute that back into the equation:
\[ \text{width} = \frac{1000}{200} \]
Calculating that gives:
\[ \text{width} = 5 \]
Thus, the width of the rectangular prism is 5.
