A cube has a side length of x feet which expression represents the surface area of the cube
A. 6x^2
B. 12x^2
C. 8x^2
D. 24x^2
B. 12x^2
6 sides, each is x^2
looks like 6 x^2 to me
The surface area of a cube is given by the formula 6x^2, where x is the side length of the cube.
The surface area of a cube is the sum of the areas of all its faces. Since a cube has six faces, each with a side length of x, the surface area of the cube can be calculated by finding the area of one face and multiplying it by six.
The formula to find the area of a square is side length squared, so the area of one face of the cube is x squared (x^2). Therefore, the surface area of the cube can be represented by the expression 6x^2.
