A cube with side length 4 centimeters is 25% full of sand. What is the volume of the sand?

Cube volume=side legnth^3

side legnth=4

volume=4^3

volume=4 times 4 times 4

volume=64

25% if full

percent means parts out of 100

25%=25/100=1/4

1/4 of 64 is sand

1/4 times 64 = sand

64/4=sand

16=sand

volume of sand=16 cm^3
