The formula for finding the surface area of a cube is 6s2, where 8 is the length of each side of the square. Evaluate for 8=10 to find the number of square centimeters (cm2) for the surface area of a cube with a side length of 10 cm
To find the surface area of a cube with a side length of 10 cm, we will substitute 8 with 10 in the formula.
Surface area = 6 * s^2
Where s is the length of each side of the square.
Substituting s = 10:
Surface area = 6 * (10)^2
Surface area = 6 * 100
Surface area = 600 cm^2
Therefore, the surface area of a cube with a side length of 10 cm is 600 square centimeters (cm^2).
step by step please
Certainly!
1. Given that the side length of the cube is 10 cm, we need to find the surface area.
2. The formula for finding the surface area of a cube is 6s^2, where s is the length of each side of the square.
3. Substitute s with 10 in the formula.
Surface area = 6 * (10)^2
Surface area = 6 * 100
Surface area = 600 cm^2
Therefore, the surface area of a cube with a side length of 10 cm is 600 square centimeters (cm^2).

Alicia works for Thomas Edison Electrical Company. She earns $100 for going to a customers house and $65 per hour, h for the job. This is modeled by 65h + 100. Evaluate for h = 3 to find how much Alicia will earn will a job that takes 3 hours.
To find how much Alicia will earn for a job that takes 3 hours, we will substitute h = 3 into the given equation.
Earnings = 65h + 100
Substituting h = 3:
Earnings = 65 * 3 + 100
Earnings = 195 + 100
Earnings = 295
Therefore, Alicia will earn $295 for a job that takes 3 hours.
A competitive cliff-diver jumps from a height of 75 feet. Find the number of feet the diver is above the ocean in 2 seconds Evaluate for t = 2 by the formula 75 - 16t 2, where t is time in seconds
To find the number of feet the diver is above the ocean in 2 seconds, we will substitute t = 2 into the given formula.
Height above ocean = 75 - 16t^2
Substituting t = 2:
Height above ocean = 75 - 16(2)^2
Height above ocean = 75 - 16(4)
Height above ocean = 75 - 64
Height above ocean = 11
Therefore, the diver is 11 feet above the ocean after 2 seconds.
