Video Summary

The problem involves calculating the combined weight of three different blocks: a rectangle, a circle, and a triangle. We know from the problem that a rectangle and a circle together weigh 200 grams, a triangle and a circle weigh 100 grams, and a rectangle and a triangle weigh 240 grams. By summing these equations, we derive that two rectangles, two circles, and two triangles weigh 540 grams in total. Dividing by 2 gives the weight for a rectangle, a circle, and a triangle: 270 grams. Thus, the combined weight of the three blocks is 270 grams.
