Answer:
80 blocks
Explanation:
Todd's tower measures 1 cm by 1 cm by 10 cm. The total number of blocks in the tower is ten and the volume of each is
[tex]1\text{ cm }\times1\text{ cm}\times1\text{ cm}=1\text{ cm}^3[/tex]
Now Aaron's block is twice as wide, twice as long, and twice as tall; therefore, its measurements are
wisth = 1 cm x 2 = 2 cm
length = 1 cm x 2 = 2 cm
height = 10 cm x 2 = 20 cm
Therefore, the volume of Aaron's block is
[tex]2\text{ cm}\times2\text{ cm}\times20\text{ cm}=80\text{ cm}^3[/tex]
Now how many blocks fit into 80 cubic cm?
The volume of one block is 1 cubic centimetre, therefore, it takes
[tex]\frac{80\text{ cm}^3}{1\text{ cm}^3}=80[/tex]
blocks to make Aaron's tower.
