Answer 2

Please consider the complete question.

A prism has a length of 9 millimeters, height of 3 and one-half millimeters, and width of 8 and one-half millimeters. What is the volume of the rectangular prism?

We know that volume of rectangular prism is product of its length, width and height.

`V=\text{Length}*\text{Width}* \text{Height}`

`V=9\text{ mm}*8(1)/(2)\text{ mm}* 3(1)/(2)\text{ mm}`

Let us convert our given mixed fraction into decimal.

`V=9\text{ mm}*8.5\text{ mm}* 3.5\text{ mm}`

`V=267.75\text{ mm}^3`

Therefore, the volume of the given prism would be
`267.75\text{ mm}^3` and option D is the correct choice.
