To find the width of a rectangular prism (also known as a rectangular cuboid) given its volume, height, and length, you can use the formula for the volume of a rectangular prism:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
In this case, you are given the following values:
- Volume = 100 cubic units
- Height = 10 units
- Length = 5 units
We can plug in these values and solve for the width:
\[ 100 = 5 \times \text{width} \times 10 \]
First, simplify the right side:
\[ 100 = 50 \times \text{width} \]
Next, solve for the width:
\[ \text{width} = \frac{100}{50} = 2 \text{ units} \]
Thus, the width of the rectangular prism is 2 units.
