The surface area goes as the edge ength squared, so if you double the edges you get four times the area
The surface area is quadrupled.
The surface area is: 600 cm2
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.
this is incorrect -- quick example.. 2"x2"x2" cube -- will have a surface area on each side of 4"sq (2x2=4) --- now make that 4"x4"x4" -- this cube will have a surface area on each side of 16"sq (4x4=16)
The cube would have a total surface area of 24 Sq. Ft.
There can be no such cube since, by definition, all edges of a cube have the same length.
There can be no such cube since, by definition, all edges of a cube have the same length.
To find the surface area of a cube, add the area of its 6 sides. The area of one side is x^2. The cube has 6 faces therefore the surface area equals 6x^2
24 sq in.
The surface area of a cube is found with the formula 6a2. Therefore, the surface area of a cube with 7 centimetre edges is equal to 6 x 72 = 6 x 49 = 294 cm2.
The surface area is 6*52 = 150 sq metres.
