Answer:
The answer to your question is z = 87 cm
Step-by-step explanation:
Data
Surface area of the rectangular prism = 8,462 cm²
Find z
Process
1.- Write and equation that help to solve the problem
Surface area = 2(13z) + 2(13)(31) + 2(31z)
-Simplify
8462 = 26z + 806 + 62z
8462 - 806 = 26z + 62z
7656 = 88z
z = 7656/88
-Result
z = 87 cm
