Answer: 976 cm^2
Step-by-step explanation: The formula for the area of a triangle is (1/2)bh
meaning you can calculate the area of two of the triangles that make up the triangular prism using 2((1/2)(14)(24)). The formula to calculate any regular quadrilateral is bh, meaning you can then calculate the two square sides of the same size using 2(10 * 25). Finally, use the formula bh to calculate the area of the base which is (14 * 10). Add up all the numbers to then get the final answer, 2((1/2)(14)(24)) + 2(10 * 25) + (14 * 10) = 976 cm^2.
