Question Analysis:
This question involves calculating the total surface area of a rectangular prism.
The main focus is applying the surface area formula using all six faces.

Key Concept Explanation:
The surface area of a rectangular prism is: 2(length × width + length × height + width × height)

Step-by-Step Solution:
lw = 5 × 3 = 15
lh = 5 × 4 = 20
wh = 3 × 4 = 12
Total Surface Area = 2(15 + 20 + 12) = 2(47) = 94 cm²
