Area of the front and back faces = 2 [ (8.1 x 8.1) + (1/2 x 8.1 x 2.1 ] = 148.23 in²

Area of the right and left faces = 2 [ 11.8 x 8.1 ] = 191.16 in²

Area of the top = 2 [4.6 x 11.8] = 108.56 in²

Total Area = 148.23 in² + 191.16 in² + 108.56 in² = 447.95 in²

Answer: Theo will need to paint about 447.95 in².
