What percent of the volume of a 10×10×10 box can be filled with 4×4×4 wooden cubes? Express your answer as a decimal to the nearest tenth.

Answer 1

2*2*2

You can not line 3 up in any direction

Answer 2

that is 8 units long by 8 wide by 8 high = 512 units cubed
out of 10 *10*10 = 1000 units cubed
so
percent = 100 (512/1000) = 51.2 %
