Answer:
False
Step-by-step explanation:
We find the volumes of the two cubes and compare them.
volume of cube = side^3
The volume of the 10-cm cube is:
V = (10 cm)^3 = 1000 cm^3
The volume of the 5-cm cube is:
V = (5 cm)^3 = 125 cm^3
1000/125 = 8
The volume of the 10-cm cube is 8 times the volume of the 5-cm cube.
The statement is false.
The answer is A.
