The shortest possible height of tower is 24 cm.
Tim used 4 blue blocks and his brother used 3 green blocks.
Step-by-step explanation:
Given,
Height of blue block = 6 cm
Height of green block = 8 cm
We will take least common multiple to find the shortest possible height.
6 = 2*3
8 = 2*2*2
LCM = 2*2*2*3 = 24 cm
The shortest possible height of tower is 24 cm.
Number of blue blocks used = [tex]\frac{24}{6} = 4[/tex]
Number of green blocks used = [tex]\frac{24}{8} = 3[/tex]
Tim used 4 blue blocks and his brother used 3 green blocks.
