We know that
[volume of a cube]=b³---------> b=∛Volume
b------> is the side length of a cube
The top block was 64 cm³------> b1=∛64-------> b1=4 cm
The middle block was 125 cm³------> b2=∛125------> b2=<span>5 cm
T</span>he biggest block was 729 cm³------> b3=√729------> b3=<span>9 cm
[</span><span>the stack of blocks tall]=b1+b2+b3-------> 4+5+9-----> 18 cm
</span><span>
the answer is
</span>the stack of blocks was 18 cm tall<span>
</span>

Answer:
80 liters
Step-by-step explanation:
24 liters is the difference between 2/5 full and 1/5 full.
Let x = number of liters in full tank.
2/5 x - 1/10 x = 24
4/10 x - 1/10 x = 24
3/10 x = 24
1/10 x = 8
x = 80
Answer: 80 liters
