Use the image to answer the question.

An illustration shows a rectangular prism joined two triangular prisms on either side. The illustration shows two identical triangular prisms, each with one side attached to the length of the rectangular prism. The sides attached to the rectangular prism are oriented such that the triangular prisms are mirror images of one another. The length of the rectangular prism is 14 centimeters. The width and the height are 5 centimeters and 4 centimeters respectively. The distance from the apex of the triangular prism to the base is 6 centimeters.

Solve for the volume of the composite figure.

The formula for finding the volume of a rectangular prism is length x width x height.

So, for the rectangular prism:
Volume = 14 cm x 5 cm x 4 cm
Volume = 280 cm3

The two triangular prisms attached to the rectangular prism are identical, so we only need to calculate the volume of one of them.

The formula for finding the volume of a triangular prism is 1/2 x base x height x length.

Base = 14 cm (length of the rectangular prism)
Height = 6 cm
Length = the side length of the triangular prism

Volume = 1/2 x 14 cm x 6 cm x side length
Volume = 42 cm x side length

Since there are two identical triangular prisms:
Total volume of both triangular prisms = 2 x 42 cm x side length
Total volume of both triangular prisms = 84 cm x side length

Now, add the volume of the rectangular prism and the volume of both triangular prisms to get the total volume of the composite figure:

Total Volume = Volume of rectangular prism + Total volume of both triangular prisms
Total Volume = 280 cm3 + 84 cm x side length

To find the value of side length, we will need more information provided in the question.

Therefore, the correct response is: 448 cm3.
are you sure
I apologize for the mistake in my previous response. Let's correct that.

First, let's calculate the volume of the rectangular prism:
Volume = length x width x height
Volume = 14 cm x 5 cm x 4 cm
Volume = 280 cm3

Next, let's calculate the volume of one of the triangular prisms:
Volume = 1/2 x base x height x length
Base = 14 cm (length of the rectangular prism)
Height = 6 cm
Length = 5 cm (width of the rectangular prism)

Volume = 1/2 x 14 cm x 6 cm x 5 cm
Volume = 210 cm3

Since there are two identical triangular prisms:
Total volume of both triangular prisms = 2 x 210 cm3
Total volume of both triangular prisms = 420 cm3

Now, add the volume of the rectangular prism and the volume of both triangular prisms to get the total volume of the composite figure:

Total Volume = Volume of rectangular prism + Total volume of both triangular prisms
Total Volume = 280 cm3 + 420 cm3
Total Volume = 700 cm3

Therefore, the correct response is 700 cm3. Thank you for bringing that to my attention.
