Answer:
64 in²
Step-by-step explanation:
Please, include the units of measurement:
"rectangular prism 4 in by 2 in by 3 in."
One side is 4 by 2 in², or 8 in²; another is 4 by 3 in², or 12 in², and the third side is 3 by 4 in², or 12 in². We have 2 of each side, so the total surface area is
A = 2(8 in² + 12 in² + 12 in²) = 2(32 in²), or 64 in²
