Answer:
8 times greater
Step-by-step explanation:
The formula of a volume of a cube:
[tex]V=a^3[/tex]
a - edge length
-----------------------------------
The edge length of cube B is a.
The edge length of cube A is 2a.
Calculate the volumes:
[tex]V_A=(2a)^3=2^3a^3=8a^3\\\\V_B=a^3[/tex]
How many times greater is the volume of the cube A than the volume of cube B?
Make the quotient:
[tex]\dfrac{V_A}{V_B}=\dfrac{8a^3}{a^3}=8[/tex]
