12'5 = 12.4166... feet
The total surface area, of all four walls, floor and ceiling is
2*(12.4166...*12.4166... + 12.4166...*10 + 10*12.4166...)
=2*(154.1736 + 124.1667 + 124.1667) = 2*402.5069 = 805.01 sq feet (to 2 dp)
For the surface area of a rectangular prism (like a non-square room) multiply each number by each other number, add them together and multiply by 2.
