Question 1064112
the rectangular blocks measures 4 by 3 by 2.


if she wants to make a cube, then each side of the cube has to be the same measure.


the least common multiple of 4 and 3 and 2 is 12.


4 * 3 = 12
3 * 4 = 12
2 * 6 = 12


assuming the height is 4 and the length is 3 and the depth is 2, they you get:


3 rectangles to form the height.
4 rectangles to form the length.
6 rectangles to form the width.


the number of rectangular blocks required would be 3 * 4 * 6 = 48.


each side of the cube would measure 12 cm.


it's very difficult to visualize, but i believe this is your answer.
