see the attachments below for the steps :)
The simplified expression is as follows:
d(-3x^2 + 9x - 14)
In order to find the volume, you have to find the volume ratio. To find the volume ratio you have to cube the scale factor. 1/2 cubed is 1/8. Now to find the volume, you multiply the volume ratio by the volume of the original prism.
160x1/8= 20
The answer is 20cm3
