Answer:

114.92 in²

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.

You have to look at a formula sheet for the surface area of different shapes and solve the equations for each side of the shape. Then add all them up
