What is the missing dimension of a rectangle or prism with the following dimensions and volume? length 3 cm width 5 cm volume 45 cm3 height? me find the height you need to find the height

Hello! 

In order to find out the volume of any prism, you are to do length x width x height.

Because we only know the length and the width, we can multiply those to get started. 3 x 5 is 15, so we know that's what we can start with.

Because we know the volume, all we have to do is do h x 15 = volume (45). Now, what is height?

In order to find the height, we must find a number that, when multiplied by 15, equals 45. 

So we can try out 3, which when multiplied by 15, equals 45. 

That means 3 is your height.

Hope I helped! :)
