To find the volume of the right rectangular prism, we start by identifying the dimensions provided:
- Length (l) = 5 inches
- Width (w) = 2 inches
- Height (h) = 8 inches
First, we calculate the area of the base (B), which is the product of the length and the width:
\[ B = l \times w = 5 , \text{in} \times 2 , \text{in} = 10 , \text{in}^2 \]
Next, we use the formula for the volume (V) of the prism:
\[ V = B \cdot h \]
Substituting the values for the base area and height:
\[ V = 10 , \text{in}^2 \times 8 , \text{in} = 80 , \text{in}^3 \]
Thus, the volume of the rectangular prism is 80 cubic inches.
