Answer is "a" (second option) Area of 1 cube face = [6 (a ÷ 4)² ] ÷ 6 which becomes a² ÷ 16 Then since Perimeter is just length² simply take the square root: sqrt (length²) = sqrt (a² ÷ 16) length = a ÷ 4 Then Perimeter × 4 = (a ÷ 4) × 4 = a
@@Imansportfolio Remember, they are asking for perimeter. That is why the side length (a/4) was extracted from the equation and all 4 sides of the square were added together to give "a". 4 • a/4 = a Yes, initial formula was for total surface area, so it was a matter of, if you can identify the value in the formula that represents the side length of the cube and use it to calculate perimeter.

A.) Is the length of one edge of the cube. B.) Is the perimeter of one face of the cube C.) Is the total length of the perimeter of four faces of the cube. D.) Is the total length of the perimeter of six faces of the cube.
Just assume a=4. Got surface area=6, which means the area of one face is 1 and the side is 1. Thus perimeter is 1*4=4, which is a. Assuming a value will make the deduction easier

6(a/4)² since we want one side we can remove the 6. So now it's (a/4)², then to find one side we find the square root of it. So now it's a/4, then to find the perimeter we multiply one side by 4 so the answer is a :)

@@TheMoonManBGk no, SAT is not about graduating from high school. It’s about demonstrating level of ability, mostly for the purposes of getting accepted into a University. The difficulties of questions range from very easy to very hard in order to distinguish poor, medium, and high levels of ability from each other. This is among the easiest SAT questions, so only getting questions like these correct would put test takers in the bottom 10% of all test takers. If I recall correctly, when I took the SAT, the questions were ordered so that the easiest questions were first. The primary difficulty with questions like the one in the video was primarily about quickly reading, understanding, and answering these questions so as not to run out of time on the harder questions. Paranoia leads a test taker to repeatedly check their answers, but this would waste too much time because the SAT is highly time constrained.
I simply thought 6×(a/4)^2=6×6^2 (a/4)^2=6^2 a/4=6 a=24 24/4=6 So 6×(24/4)^2=6×(6)^2=6^3 So a had to be the perimeter of one face bc a divided by 4 had to be six, since 6^2=36=24/4=a/4
So a cube has 6 faces So firstly divide by 6 Then he wants the perimeter so take the square root now we have a/4 But remember perimeter is one deminsional so what you got is the length of only one of the edge and you have four edges so 4•a/4 now 4/4=1 so we get 1a=a The answer is a but not A
The only thing in the formula that you don't do in surface area is deciding be 4 and for the formula to work a divided by four has to equal the length of an edge there fore a is already the primeter

Haha even my 8th Grade geometry questions were way harder than this
If you think about it the formula of a cube is (s^2)+(s^2)+(s^2)+(s^2)+(s^2)+(s^2)= sa
Answer is "a" (second option)
Area of 1 cube face = [6 (a ÷ 4)² ] ÷ 6
which becomes a² ÷ 16
Then since Perimeter is just length² simply take the square root:
sqrt (length²) = sqrt (a² ÷ 16)
length = a ÷ 4
Then Perimeter × 4 = (a ÷ 4) × 4 = a
"One of the easiest questions."
