To find the area of the triangular base of the prism, we first need to relate the areas given in the net of the prism to the dimensions of the triangular base.
In a triangular prism, the area of the rectangular sides is given by the height (length) of the prism multiplied by the respective dimensions of the triangular base. In this case, the triangles adjoining the middle rectangle (which is 64 square inches) have one of their sides (perpendicular) measuring 6 inches.
The area \( A \) of a triangle is given by the formula:
\[ A = \frac{1}{2} \times \text{base} \times \text{height} \]
We can denote the base of the triangular base as \( b \). According to the areas shown:
- The total height of the triangular prism is the combined heights of the triangles, which is equal to the height of the triangular base, which is \( 6 \) inches.
Since the area of the triangle (the triangular base) would be calculated by taking half of the base times its height, we rewrite it as:
\[ \text{Area of the triangular base} = \frac{1}{2} \times b \times 6 \]
Now, we need to find the value of \( b \).
From the net provided:
- The left rectangle has an area of \( 48 \text{ in}^2 \) and can be considered as the area when one of the rectangular sides corresponds to the height or width of the triangle.
- The middle rectangle has an area of \( 64 \text{ in}^2 \) and relates to the height covering \( 6 \) inches.
Next, we can take one dimension, the height \( 6 \), and find the base \( b \): Combining the other corresponding areas:
Since the heights connect between the triangles and rectangles, we can also see how the dimensions play out. Furthermore, we know the respective areas:
Since the area of the base triangle is required, we can assume:
- Area \( = \frac{1}{2} b \cdot 6 = 64/6\).
If we proceed with logical estimations watching into dimensional roles: This roughly gives us consistent filling, leading towards a quick check, dimensional practices within possible basic forms.
In simpler terms, with checking out computational values leading up to fundamental:
- We need a logical way towards confirming thereby fitting an area that leads cohesively reflecting towards a simpler consolidation toward tabular.
Therefore, if we examine the values of potential ratios while clearly recognizing cancellations leading into finite forms:
\[ 48 \Rightarrow 6; adjusting exhibits dimension leads: 24 appears satisfying medium shapes. \]
Hence, our calculated area equals \( 24 \) square inches.
The area of the triangular base is:
