An illustration showing a house shaped structure with a doorway in the center. The left and right sides of the house form cubes labeled 4 inches in height, length and width. The doorway is 6 inches wide. A dashed line runs from the top center of the doorway to the triangular apex of the house and is labeled 4 inches.
What is the volume of the composite figure?

To find the volume of the composite figure, we need to calculate the volume of each individual component and then add them together.
The volume of each cube is given by V = l x w x h, where l is the length, w is the width, and h is the height.
Volume of each cube = 4 x 4 x 4 = 64 in.3
Total volume of both cubes = 2 x 64 = 128 in.3
The volume of the triangular prism on top of the cube is given by V = 1/2 x b x h x l, where b is the base of the triangle, h is the height of the triangle, and l is the length of the prism.
Volume of the triangular prism = 1/2 x 6 x 4 x 4 = 48 in.3
Total volume of the composite figure = 128 + 48 = 176 in.3
Therefore, the correct answer is 176 in.3.

My apologies for the mistake in my previous responses. Let's correct it.
To find the volume of the composite figure, we need to find the volume of each component and add them together.
Volume of each cube:
V = 4 inches x 4 inches x 4 inches = 64 cubic inches
Since there are 2 cubes, the total volume of cubes = 2 x 64 = 128 cubic inches
Volume of the triangular prism:
The base of the triangle is 6 inches wide and the height (from the top center of the doorway to the apex) is 4 inches.
V = 1/2 x base x height x length = 1/2 x 6 inches x 4 inches x 4 inches = 48 cubic inches
Total volume of the composite figure:
128 cubic inches (cubes) + 48 cubic inches (triangular prism) = 176 cubic inches
Therefore, the correct answer is 176 in.3. Thank you for your patience.
