Answer 6

Composite figures need to be broken down into a different shape to find certain calculations, such as volume. The shape on top is the composite figure, since it's simple to find the formula for the rectangular prism underneath it. Do you have the volume for the rectangular prism?

Answer 7

160 right?

Answer 9

Sorry something came up. Yes, that's right. For the top shape, you can see that the bottom has the same dimensions as the rectangular prism, in regards to length and width. You can change that top shape into another rectangular prism, by doing the same length x width x height, and dividing by 2.
