Q. A=6s2The formula gives the surface area A of a cube with side length s. What is the surface area of a cube with side length of 23 units?
Identify formula for surface area: Identify the formula for the surface area of a cube.The formula for the surface area of a cube is A=6s2, where s is the side length of the cube.
Substitute given side length: Substitute the given side length into the formula.The given side length is s=23 units. Substitute this value into the formula to find the surface area.A=6×(23)2
Calculate square of side length: Calculate the square of the side length.(23)2=(23)×(23)=49
Multiply by 6 for surface area: Multiply the result by 6 to find the surface area.A=6×(49)A=454
Simplify fraction for final area: Simplify the fraction to get the final surface area. 454 can be simplified by dividing both the numerator and the denominator by 2.A=227
