the edges of a cube are 3 inches long. what is the surface area, in square inches, of this cube?
How many sides does a cube have?
isn't the area of one of those sides 3x3 or 9 square inches?
......
To find the surface area of a cube, you can use the formula: Surface Area = 6 * (edge length)^2.
Given that the edge length of the cube is 3 inches, we can substitute this value into the formula:
Surface Area = 6 * (3 inches)^2
Now, let's calculate the surface area:
Surface Area = 6 * (9 inches^2)
Surface Area = 54 square inches.
Therefore, the surface area of the cube is 54 square inches.
To find the surface area of a cube, you need to calculate the total area of all six faces of the cube.
The formula for the surface area of a cube is: Surface Area = 6 * (edge length)^2
In this case, the edge length is given as 3 inches. So, we can substitute the value into the formula:
Surface Area = 6 * (3 inches)^2
Calculating the square of 3:
Surface Area = 6 * 9 square inches
Finally, performing the multiplication:
Surface Area = 54 square inches
So, the surface area of the cube is 54 square inches.
