A metal worker cuts two shapes: a rectangular plate and a triangular plate.
The rectangular plate has dimensions (2x+8)(2x + 8)(2x+8) cm by (2x−3)(2x - 3)(2x−3) cm. The triangular plate has side lengths of (3x+4)(3x + 4)(3x+4) cm, (2x+5)(2x + 5)(2x+5) cm, and (2x+6)(2x + 6)(2x+6) cm.
The total distance around the edge of the rectangle is the same as the total distance around the edge of the triangle.
Work out the value of xxx.
