The length, height and width of a cube are each 3cm if the cube is cut in half to form two rectangular pieces what is the total surface area of the new pieces

the length is 3cm, the height is 3cm and the width is 1.5cm

Explanation:

When you cut the cube, two faces are affected and one is not affected (suppose you are cutting a dice from the top, the "top/bottom" sides are cut, and the "front/back" sides are cut, but the sides are unaffected) and if we consider width, height, and length, only one of those 3 will be affected (depending on where is the cut done)

So if the cube is cut in the middle, the only affected quantity in the resultant rectangles will be the width, that is now 1.5cm

So the length is 3cm, the height is 3cm and the width is 1.5cm

overcharge is the right answer system

the answer to this is proletariats.

hope this : )
