Understanding the Problem

The given object is symmetrical through the Z-axis. To find the area of the object, we need to calculate the area of the two triangular faces and add them together. The given dimensions are Y = 18 inches, Z = 19 inches, and H = 11 inches.

Breaking Down the Object

The object can be divided into two triangular faces, each with a base of 18 inches and a height of 11 inches. The two faces are mirror images of each other, so we can calculate the area of one face and multiply it by 2 to get the total area.

Calculating the Area of One Face

To calculate the area of one triangular face, we can use the formula:

Area = (base × height) / 2

In this case, the base is 18 inches and the height is 11 inches. Plugging in the values, we get:

Area = (18 × 11) / 2 Area = 198 / 2 Area = 99 square inches

Calculating the Total Area

Since the object has two triangular faces, we can multiply the area of one face by 2 to get the total area:

Total Area = 2 × 99 Total Area = 198 square inches

However, this is not one of the answer choices. Let's re-examine the problem and see if we can find the correct solution.

Re-examining the Problem

Upon closer inspection, we can see that the object is not just a simple triangular face. It has a rectangular base with a length of 18 inches and a width of 19 inches. The height of the object is 11 inches.

Calculating the Area of the Rectangular Base

To calculate the area of the rectangular base, we can multiply the length and width:

Area = length × width Area = 18 × 19 Area = 342 square inches

Calculating the Area of the Triangular Faces

The object has two triangular faces, each with a base of 18 inches and a height of 11 inches. We can calculate the area of one face and multiply it by 2 to get the total area:

Area = (base × height) / 2 Area = (18 × 11) / 2 Area = 198 / 2 Area = 99 square inches

Calculating the Total Area

To calculate the total area, we need to add the area of the rectangular base and the area of the two triangular faces:

Total Area = Area of rectangular base + 2 × Area of triangular face Total Area = 342 + 2 × 99 Total Area = 342 + 198 Total Area = 540 square inches
