The answer to your question is 566 m²

Step-by-step explanation:

Data

length = 19 m

width = 4 m

height = 9 m

Process

1.- Calculate the area of the 6 faces

-Area of the bases

Area = 19 x 4 x 2 = 152 m²

-Area of the lateral faces

Area = 4 x 9 x 2 = 72 m²

-Area of the frontal and the opposite faces

Area = 19 x 9 x 2 = 342 m²

2.- Calculate the total area

Total area = 152 + 72 + 342

                 = 566 m²
