do we multiply these too? @k_lynn

D, you multiply the numbers together to get your answer.

thanks :) @thedj4JC

k_lynn · Answer

The volume formula for this would be $$\frac{ 1 }{ 2 }\times Base \times Height \times Length$$

thedj4jc · Answer

No problem!!

k_lynn · Answer

You can't just multiply all the numbers together, that will give you an incorrect answer.  You have to multiply by 1/2 also.
