Answer:
Sam is 24; his mom is 48.
Step-by-step explanation:
We can let x and y represent Sam's age and his mom's age, respectively.
y = 2x . . . . . Mom is twice Sam's age
y -12 = x + 12 . . . . Mom's age 12 years ago is the same as Sam's age 12 years from now
__
Substituting for y in the second equation, we have ...
2x -12 = x + 12
x = 24 . . . . . . . . . add 12-x to both sides
y = 2(24) = 48
Sam is 24; his mom is 48.
If you are trying to find the surface area I believe it would be 3456 inches. You would do 24 X 24 to get 576 because the formula to get the area is Length times width. Then you would do 576 times 6 because the cube has 6 sides and you would multiply it by the number of sides because each would be the same, cubed are the same length all around. Hope this helped.
