The formula form the surface area of a cube is SA=6s^2 where s represents the length of a side of the cube. What is the surface area of a cube with the sides 4.5 centimeters long?
SA = 6 (4.5 cm)^2 =
4.5cm^2 = 20.25cm^2
20.25cm^2*6= 121.5 cm^2

To find the surface area of a cube with side length 4.5 centimeters, we can use the formula SA = 6s^2, where s is the length of a side of the cube.
Substituting s = 4.5 into the formula, we have:
SA = 6(4.5)^2
Now, let's calculate the surface area:
SA = 6(20.25)
SA = 121.5
Therefore, the surface area of a cube with sides 4.5 centimeters long is 121.5 square centimeters.
To find the surface area of a cube, we can use the formula SA = 6s^2, where SA represents the surface area and s represents the length of a side of the cube.
In this case, the length of each side is given as 4.5 centimeters. We substitute this value into the formula:
SA = 6 * (4.5)^2
First, we square the length of the side: (4.5)^2 = 20.25
Then, we multiply this by 6: SA = 6 * 20.25 = 121.5
Therefore, the surface area of a cube with sides 4.5 centimeters long is 121.5 square centimeters.
