422 in²
Step-by-step explanation:
The surface area of a figure can be found using the general formula:
SA = 2ab + 2bc + 2ac, where 'a, b, c' are the side lengths of the object
Using the given dimensions, assign variables:
a = 12
b = 5
c = 8
Plug these into the equation:
SA = 2 (12*5) + 2 (5*8) + 2 (12*8)
SA = 150 + 80 + 192 = 422 in²
