Answer:
The statements that are true
A.) Six of the one half cubes would have a volume of 3 cubic units.
D.) Three of the one-third cubes will make 1 unit cube.
E.) Two of the one-half cubes will make 1 unit cube.
F. Both stacks will have a volume of 3 cubic units.
Explanation:
Complete, Correct Question
Marissa claims that stacking 6 blocks with dimensions of (½×1×1) will give the same volume as stacking 9 blocks with
dimensions of [(1/3)×1×1] Which statements about her claim are true? Check all that apply.
Before checking the statements, we first find the volume of both cars of blocks
Volume of a cuboid block = lbh
For block A, volume = (1/2) × 1 × 1 = (1/2) cubic units
6 block A's will have a volume of 6 × (1/2) = 3 cubic units.
For block B, volume = (1/3) × 1 × 1 = (1/3) cubic units
9 block B's will have a volume of 9 × (1/3) = 3 cubic units.
Now checking the statements one at a time
A. Six of the one half cubes would have a volume of 3 cubic units.
As calculated above, this is true.
B. Nine of the one-third cubes would have a volume of 6 cubic units.
This is false. 9 of the one-tailed cubes has a volume of 3 cubic units too not 6 cubic units.
C. Since 1/2 and 1/3 do not have common factors, stacks of one-half cubes and stacks of the two cubes could never have the same volume.
From the calculation before analysing the statements, the two stacks mentioned had the same total volume of 3 cubic units. Hence, it shows this statement is false.
D. Three of the one-third cubes will make 1 unit cube.
3 one-third cubes will have a volume of
3 × (1/3) = 1 cubic unit. This statement is true.
E. Two of the one-half cubes will make 1 unit cube.
2 one-half cubes will have a volume of
2 × (1/2) = 1 cubic unit. This statement is true.
F. Both stacks will have a volume of 3 cubic units.
From previous calculation before analysing the statements one at a time, this is true. The total volume of both stacks mentioned today is 3 cubic units.
Hope this Helps!!!
