Eight little cubes.
You need three measures of length to determine the surface area - the length, width and height.
112 cm squared
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.
base x height = area 2 cm x 2cm = 2cm^2 (squared) :)
12 cm3
A cube has six square faces. This cubes faces are 2 x 2 ie 4cm2 so overall surface area is 24 cm2.

112 cm squared
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
A cuboid is a 3 dimensional object and 3 measures are required for the total surface area of a cuboid.
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.
base x height = area 2 cm x 2cm = 2cm^2 (squared) :)
If you assume that the shape is a cuboid, its area is 10 cm2 and its volume is 2 cm3
Not enough information given.
Such a box has four sides each with an area of 8 cm2 and two end each of are 4 cm2 for a total of 36 cm2 , assuming the box has a top and you want only the outside area.
