Determine the total area of the TWO bases of this triangular prism.

To find the total area of the two bases of the triangular prism, we need to first calculate the area of one base and then multiply it by 2.

The triangular base of a prism is a triangle, so we can use the formula for the area of a triangle:
Area = (base x height) / 2

For the first base:
Area = (10 x 8) / 2 = 40 square inches

For the second base:
Area = (12 x 14) / 2 = 84 square inches

Now, add the areas of the two bases:
40 + 84 = 124 square inches

The total area of the two bases of the triangular prism is 124 square inches.
