I take it you mean the surface of the cuboid of those dimensions.
A quick sketch on paper, as you can't create it in a simple text editor, helps in cases like this.
Taking the 2 x 2 faces first, their total area = 2 x (2 x 2) = 8 cm^2
Now the 2 x 1 faces: 4 x ( 2 X 1) = 8cm^2.
So total surface area of the cuboid = 8 + 8 = 16 square centimetres.

Eight little cubes.
What is the total volume of 1Cm x 2Cm x 2Cm?
If the shape is a cuboid, then the volume is 4 cubic centimetres.
What is the surface area of a cylinder whose radius is 2Cm and height is 8Cm?
A cylinder whose radius is 2cm and height is 8cm has a total surface area of approximately 125.66cm2 {ADDED} To explain that further, the formula is pi*r^2 X h where r is the radius and h the height.
What is the area of a rectangular box 2by4by1 cm?
Volume of a cuboid = widthxlengthxheight; therefore V = 2cm x 4cm x 1cm = 8cm3

What shape of an area of 6cm2?
Any shape you want as long as the area within its boundary is 6cm2.examples:a triangle of base 6 cm and height 2 cm;a rectangle 2cm by 3 cm;an L shaped hexagon with sides 5cm, 2cm, 1cm, 1cm, 4cm, 1cm;circle of radius approx 1.382 cm;
What is cubiccentimetar?
a cubic centermeter is the size of a cube 1cm X 1cm X 1cm. A cube sized 2cm X 2cm X 2cm has a size of 8 cubic centermeters it is not cubiccentimetar..... it is cubic centimeter.... it is nothing but the cube of one cenimeter got... (i.e) cm3
What is the surface area of a 2cm x 2cm x 2cm cube?
A cube has six square faces. This cubes faces are 2 x 2 ie 4cm2 so overall surface area is 24 cm2.
The volume of a cube is 8 cm3 What is the surface area of this cube?
Volume = 8 cm3 so each side = 2 cm So area of one face = 2cm * 2cm = 4 cm2 So total surface area (6 faces) = 6*4 cm2 = 24 cm2
