assuming you mean the cube has 6cm sides....
each face of the cube has an area of 6cm x 6cm = 36cm2
A cube has 6 faces so the total surface area is 6 x 36 = 216cm2
It is 12*12*6 = 864 square cm
A cube has six faces. Therefore, its surface area is 6 times a face's area.The area of a square whose edges measure 9 cm is 81 cm2.Therefore, the surface area of a cube whose edges measure 9 cm is 6*81 = 486 cm2.
If the side is s cm long then the volume is s3 cm3. So s3 = 343 cm3 and therefore, s = 7 cm. Then the surface area is 6*s2 = 6*49 cm2 = 294 cm2
The surface area of the cube will be 54cm2To find the surface area for other cubes, take the edge length (x) and square it (x2) and then multiply that by six: x2*6 = surface area.
A cube has 6 faces and each face is square, so the answer is 6*11*11 sq. cm.
