Use the unit circle to find sin90°

Hello!

To find the Volume, you'll need to multiply all of the measurements together. So you'll need to multiply 12, 16, and 13 together to get the Volume. First, let's multiply 12 and 16 together to get 192

192*13

Now you're left with 192*13. After you've multiplied them together you should get 2496

You should now have a Volume of 2496in³

I hope this helps!
