• marissa claims that stacking 6 blocks with dimensions of one-half times 1 times 1 will give the same volume as stacking 9 blocks with dimensions of one-third times 1 times 1. which statements about her claim are true? check all that apply. six of the one-half cubes would have a volume of 3 cubic units. nine of the one-third cubes would have a volume of 6 cubic units. since one-half and one-third do not have common factors, stacks of one-half cubes and stacks of third-cubes could never have the same volume. three of the one-third cubes will make 1 unit cube. two of the one-half cubes will make 1 unit cube. both stacks will have a volume of 3 cubic units.
