1 and 2 over 3 cubic inches
Answer:
8
Step-by-step explanation:
since it is a cube the all sides are equal
v=a³
512 = a³
a=³√512
a=8
the length of the rock=8
a + a + a is the same as multiplying a by 3 so you would have 3a
b + b is the same as multiplying b by 2 so you would have 2b
Combing everything together you would have the final answer of :
3a + 2b + c
No, because the size of their respective dimensions are not proportional
