Sorry Im in 6th but i still have no idea......
Forty and ninety nine hundreths
C because x is positive so it moving right and y is positive so it moves up
The correct answer is: [A]: " 384 in² " .

Explanation:
______________________________________________________
The formula for the surface area of a cube is:
______________________________________________________
→ A = 6a² ;
______________________________________________________ → in which:
______________________________________________________
A = surface area of the cube— for which we shall solve ;
(in "square units" ; or, " in² " ; in our case) ;
a = side length = " 8 in " (given);
→ Note: A cube has all equal side lengths.
→ The "6" in the formula accounts for "6 sides" of a cube.
_______________________________________________________
→ To solve for the surface area of the cube; plug in our known value(s);
& solve; as follows:
_______________________________________________________
→ A = 6 a² ;
= 6 * (8 in)² ;
= 6 * 8² * in² ;
= 6 * 8 * 8 * in² ;
= 48 * 8 * in² ;
= 384 in² ;

The answer is: " 384 in² " ;
→ which is: Answer choice: [A]: " 384 in² " .
