A number of rectangles can be made with the full set of pieces.

The construction below can be used to make pentuplications of all 35 hexominoes.Quadruplication of a dekomino with a hole in the shape of the dekomino.Ttwo quadruplicated pentominoes with a hole in the shape of the pentomino.1-2-3-4 problem. Take one of the pentominoes in the set and with the rest make double- triple- and quadruple-sized replicas.1-1-2-3 problem. Create an area of 10 square units, produce a copy, a duplication and a triplication.3-4 problem. With the whole set produce simultaneous triplication and quadruplication of an hexomino.1-2-5 problem - take one pentomino from the set and then with the remaining pieces create double and fivefold replicas.7-8 problem. Remove one heptomino and one octomino from the set and with the remaining pieces makes simultaneous triplications of both pieces.Three twins problem - create three sets of pairs of congruent shapesTwo triplets problem - create two sets of three congruent shapesQuintuplets - create 5 congruent shapes each with area 30Sextuplets - create 6 congruent shapes each with area 25Make two 9x9 squares with a hole in each in the shape of an hexominoMake a 12x13 rectangle with a hole in the shape of an hexomino. All 35 problems are likely to be possible.Sets of squares
