Answer:

952 ft²

Explanation:

bottom surface: rectangle

area = 10 ft × 14 ft = 140 ft²

front and back surfaces: rectangle and triangle (2 equal surface areas)

area = ( 10 ft × 10 ft + 10 ft × 8 ft / 2 ) × 2 = 280 ft²

right and left vertical surfaces: rectangles (2 equal surface areas)

area = 14 ft × 10 ft × 2 = 280 ft²

right and left tilted surfaces: rectangles (2 equal surface areas)

area = 14 ft × 9 ft × 2 = 252 ft²

total surface area = 140 ft² + 280 ft² + 280 ft² + 252 ft²

total surface area = 952 ft²
