First, we need to find the base of the triangular prism. The base is made up of two right triangles, so we can find the base area by summing the areas of the two triangles.

Let one of the right triangles have legs a and b, and the other one have legs b and c.

Given that the sum of the areas of the rectangles is 48 + 64 + 80 = 192 inches^2.

The area of a rectangular is given by the formula:

Area = (1/2) * base * height

where the height of the triangles is 6 inches.

Therefore, the area of one of the right triangles is (1/2) * a * 6 = 3a, and the area of the other triangle is (1/2) * c * 6 = 3c.

The total area of the triangular base is then:

Total area = 3a + 3c

Given that the total area is 192 inches^2, we can then have:

3a + 3c = 192

We can further simplify the equation to:

a + c = 64

Since the area of the right triangle is given as b * c = 64, we can find the two possible sets of values for a and c. Here are two possible set of dimensions that could satisfy these conditions:

a = 32 inches, c = 32 inches

a = 40 inches, c = 24 inches

Therefore, the area of the triangular base is either 32 * 6 = 192 inches^2 or 40 * 6 = 240 inches^2.
