Question

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​

Answer 1

The surface area of the new piece would be 4.5

Step-by-step explanation:

I got this answer because if you cut 3cm in half you get 1.5 and the you have to must multiply the side that stay the same by the one that was cut in half which is equivalent to 4.5 thats how i go the surface area

hope that helped!

Answer 2

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

Step-by-step 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
