Answer:
The answer to number 4 would be 576cm^3
Explanation:
Number 4:
The formula for volume would be V=B·h
to find B your going to find the base of the triangle which would be B=1/2·8·9 so B=36
Then you find the height which is 16 because it connects the two bases of the triangular prism
Next you multiply B·h so 36·16
Lastly, add your units and cube the number because you are foinding volume.
