X=24
First you find the third side of the smaller triangle by using the Pythagorean theorem. You find that is it 100. Then you subtract that from 26 squared. After you get that, you square root the answer to get 24
Surface Area of the top and bottom = 2 x 8 x 3 = 48 in²
Surface Area of the lateral side rectangle = (8 + 8 + 3 + 3) x 5 = 110 in²
Total Surface Area = 48 + 110 = 158 in²
Answer: 158 in²
