The surface area is 804.25 cm2
Area = 2pir2 + 2pirh Area = 2pi(3 cm)2 + 2pi(3 cm)(10 cm) = 245 cm2 -------------
1 cm2= 100 mm2
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
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.
Total surface area is 905 cm2
Total surface area is 903.77 cm2
188.4 cm2
SA = 904.78 cm2
125.7 cm2
Total SA = 1,256.6 cm2
The surfave is 653,12 cm2 (if your unit is centimetre).
Total SA = 245.04 cm2
1809.56 cm2

The surface area of a 7 cm cube is 294 cm2
The question seems to be asking what the surface area of 6 cm2 is. The answer is, 6 cm2!
