A wooden wedge is used to prop open a door. The wedge is a right triangular solid that is 8 cm long, 6 cm high (those are the measures of the legs of the triangle) and has a depth of 2 cm. It is wedged under a door that has 3 cm clearance between the bottom of the door and the floor. What percent of the volume of the wedge is under the door?

X=3y-6
2(3y-6) + 5y = 21
6y - 12 + 5y = 21
11y = 33
y = 3

Therefore x = 3(3) -6
x = 3
