Answer: 729 centimeters cubed
Step-by-step explanation: a square always has an equal amount of length and width, and we know that the cube's volume can be solved with L x W x H, so this means we can plug in 9 x 9 x 9 into our formula. 9 x 9 = 81. 81 x 9 = 729. 729 centimeters cubed is your correct answer.
