Imade a fort for my pet gorilla by connecting two boxes. the first box is 555 meters long, 999 meters wide, and 999 meters high. the second box is 333 meters long, 888 meters wide, and 222 meters high. how many cubic meters of space does my gorilla have to play in her fort?

For each proportion find the unknown number x 1/5/8=×/15

Which shows the correct substitution of the values a, b and c from the equation 1=-2x+3x^2+1
