This makes a right triangle with hypotenuse x+2 and legs 10 and x
10²+x²=(x+2)²
100 + x² = x²+4x+4
100=4x+4
4x=96
x=24, the height we are looking for

Answer: 54
Why? You need to put 3 in for x so you get
2(3)^3 
3 to the third power is 3*3*3 which equals 27
2(27)
Now you must do 2 times 27 and you get 54
Hope this helps
