Javier is building a rectangular case that has a length of 28 centimeters, a width of 20 centimeters, and a height of 14 centimeters. He decides to change the height to be 2 times the original height.
What will happen to the volume of the case when the height is changed?

What am i doing here. add?

I’m not sure about that

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
