If the solid figure was cut along the dotted line, which statements would be true? check all that apply. nothing would change. the surface area would increase. the volume would remain constant. the surface area would decrease. the volume would increase.

Only the surface area will increase, volume will stay same.

Explanation:

You will observe when an orange is cut in to two, each half will have one more plane surface than the orange had before it was cut. So surface area will definitely increase.

Now consider a water bottle. Cut it in to two from center and check whether you can put more water in the bottle than it was in one piece.Surely you will not, that is because the volume is not changed as a solid is being cut.

Therefore,

Only the surface area will increase, volume will stay same.
