You would wana use SA=2lw+2lh+2hw
so SA=2(8×2)+2(8×12)+2(2×12)
make the calculations than mention how you find the surface of one side of the box than the whole surface area by using that formula
Answer:
What is 20 percent of 500.? = 100.
Step-by-step explanation:
3 / 5 = (x+1) / (y-2)
↓
↓ multiply by 5 / 3
↓
1 = 5 * (x+1) / 3 * (y-2)
↓
↓ move and simplify
↓
5x + 5 = 3y - 6
↓
↓ minus 5
↓
5x = 3y - 11
↓
↓ divide by 5
↓
Answer : x = (3y - 11) / 5
