To find the height 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 = 1.5 in³
- Length × Width = 1.5 in²
Let:
- \( h \) = height of the prism
Using the volume formula, we can set up the equation:
\[ 1.5 = 1.5 \times h \]
To find \( h \), we can divide both sides of the equation by 1.5:
\[ h = \frac{1.5}{1.5} = 1 \]
Thus, the height \( h \) of the prism is:
\[ \boxed{1 \text{ in}} \]
