A cube has a volume of 729 cubic centimeters. What can be concluded about the cube? Check all that apply. Recall the formula mr021-1.jpg. The side length, s, can be found using the equation mr021-2.jpg This is a perfect cube. The side length is 243 centimeters. The side length is 9 centimeters. Taking the cube root of the volume will determine the side length. If you multiply the volume by three, you can determine the side length.

Without multiplying, determine the sign of the product (356,864)(−194,758). The sign of the product is positive because a positive multiplied by a negative is a positive. The sign of the product is negative because a positive multiplied by a negative is a negative. The sign of the product is negative because the second number is negative. The sign of the product is positive because the first number is positive.
