Answer 2

do you know to do this

Answer 3

would it be the third on

Answer 4

yes

Answer 5

it would be

Answer 6

The third choice is not the answer.

To find the volume (V) of any rectangular prism, use the equation V = L x W x H. L is the length, W is the width, and H is the height.

The question gives you 3 variables already and you're asked to find the 4th. What would the height be using this equation?

Answer 7

oh but i still dont know how to get the hieght

Answer 8

Well you just need to rearrange the equation to solve for height:

\[H={V \over L \times W}\]
If you plug in V, L, and W, what do you get for H?

Answer 9

oh ok
