A cube has edges measuring 4 cm long.
Calculate the surface area of the cube.
A cube has edges measuring 4 cm long.
Calculate the surface area of the cube.
In order to find the surface area of the cube, we need to understand that a cube has 6 identical square faces.
The formula for the surface area of a cube is given by:
where is the length of an edge of the cube.
According to the problem, each edge of the cube is 4 cm long. We can substitute this value into the formula:
This simplifies to:
Performing the multiplication gives us:
Thus, the total surface area of the cube is .
Therefore, the correct answer is , which corresponds to choice 2.
