Savannah made ice cubes for a party. each ice cube measured 20 mm by 20 mm by 20 mm. how much water was needed to make each cube?

I am assuming you need to find the volume since you need to find the amount of water. In real life the amount of water would be more than the volume of the ice. But as an estimate we can use volume.

To find the volume you multiply the 3 dimensions- length, width and height. 20 times 20 is 400. 400 times 20 is 8000 mm. So about 8000 mm water was needed.

Hope this helps! Brainliest Appreciated

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
