Answer:
60cm^2
Step-by-step explanation:
1. turn triangle into rectangle measuring 15x8
2. find area of rectangle (area = base*height): 8*15 = 120
3. Find area of triangle (divide rectangle area by 2): 120/2 = 60cm^2

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 " .

Answer:
D. in quadrant III
Step-by-step explanation:
The signs of the coordinates tell you the point is located left of, and below, the origin (where the axes cross). That puts it in Quadrant III.
