Step-by-step explanation:
The first application of the Pythagorean theorem is used to find the diagonal of one face. That is called 'a' in this problem. Then the second application of the Pythagorean theorem uses that value of 'a' along with the remaining prism dimension to find the space diagonal 'c'.

You don't actually have to find 'a', because you only need the value of a². Using the first equation to substitute into the second equation gives ...
6² +8² +12² = c²
Answer:
99
Step-by-step explanation:
8x-13+7x-17=180( because stright angle = 180 degree)
15x-30=180
15x=210
x=14
8(14)-13= 99
Answer:
this systems shows only one solution... not no solution.
