The lateral faces of the triangular prism are in the shape of triangles. The formula to calculate the area of a triangle is 1/2 * base * height.
Given that the base of the triangle is 9 inches (the length of the top/bottom of the prism) and the height of the triangle is 1.5 inches (the height of the prism), the area of each lateral face is:
1/2 * 9 * 1.5 = 6.75 square inches
Since there are two lateral faces on the prism, the total amount of white cardboard needed to make one pizza container is:
6.75 * 2 = 13.5 square inches
Therefore, 13.5 square inches of white cardboard is needed to make one pizza container.
