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.

Volume of a cuboid = widthxlengthxheight; therefore V = 2cm x 4cm x 1cm = 8cm3

If the shape is a cuboid, then the volume is 4 cubic centimetres.
base x height = area 2 cm x 2cm = 2cm^2 (squared) :)
A cube has six square faces. This cubes faces are 2 x 2 ie 4cm2 so overall surface area is 24 cm2.

The surface area of a cuboid is the sum of all the areas of all its faces: 2 ends + 2 fronts + 2 tops = 2 x (area_of_end + area_of_front + area_of_top). For a 2cm x 3cm x 5cm cuboid, the surface area is: 2 x (2 x 3 + 2 x 5 + 3 x 5) cm3 = 2 x (6 + 10 + 15) cm3 = 2 x 31 cm3 = 62 cm3
Volume of a cuboid = widthxlengthxheight; therefore V = 2cm x 4cm x 1cm = 8cm3
A cube has all sides of length 2cm. What is the surface area and volume of the cube?

base x height = area 2 cm x 2cm = 2cm^2 (squared) :)
Surface area of a cuboid with sides x, y and z is 2(xy+yz+zx) So surface = 2*(1.45*1.45 + 1.45*5 + 5*1.45) = 2*16.6025 = 33.205
The surface area is the total area of all the faces. For a cuboid, all these faces will be rectangular. Example: Find the surface area of a 2 x 4 x 5 cm cuboid. The area of the faces will be: 2 x 4 = 8 cm2 2 x 5 = 10 cm2 4 x 5 =20 cm2 Adding these up give an area of 38 cm2. However we now need to multiply our answer by 2 as there are exactly two of each face. So our final answer is 38 x 2 = 76 cm2.
Add all the area of six faces of the box in gerneral the surface area of a cube shape box is 6a2 and of cuboid is 2(lb x bh x hl)
A cube has 6 faces each face is area 2x2 = 4 square cm surface area = 6 x 4 = 24 sq cm
