Answer:
114.92 in²
Step-by-step explanation:
There are 5 faces: three rectangles and two triangles.
The area of the base rectangle is 5 × 9.4 = 47.
The area of the larger rectangle on top is 5 × 7.2 = 36.
The area of the smaller rectangle on top is 5 × 3 = 15.
The area of each triangle is ½ × 9.4 × 1.8 = 8.46.
The total area is:
47 + 36 + 15 + 8.46 + 8.46 = 114.92.
