Arectangular prism has a length of 1/2 m, a width of 1/2 m, and a height of 6 m. how many unit cubes with edge lengths of 1/2 m does it take to fill the prism?

The "unit cube" fills the length and width, so we must find how many it takes to fill the height.
.. (6 m)/(1/2 m) = 12

It will take 12 "unit cubes" to fill the prism.

The length is 23 and y because you add them together

The answers 5 so there’s the you need trust me it’s right
