Understanding Cube Volume and Percent Increase

Which of the following best describes a cube?

• A three-dimensional figure with circular faces.

• A three-dimensional figure with rectangular faces.

• A two-dimensional figure with four equal sides.

• A three-dimensional figure with equal-length edges.

What is the formula for the volume of a cube?

• Length + Width + Height

• Length + Width

• Length x Width x Height

• Length x Width

What happens to the volume of a cube if all its edges are doubled?

• The volume decreases.

• The volume remains the same.

• The volume increases eightfold.

• The volume doubles.

If a cube has a side length of 1, what is its volume?

• 8

• 2

• 4

• 1

What is the volume of a cube with side length 2?

• 8

• 6

• 4

• 2

What is the percent increase if a volume doubles?

• 200%

• 300%

• 100%

• 50%

If a cube's volume is increased by 300%, what is the new volume if the original was 1?

• 1

• 2

• 3

• 4

If a volume increases from 1 to 8, what is the percent increase?

• 700%

• 200%

• 100%

• 800%

How do you calculate the percent increase from an original to a new amount?

• Add the original and new amounts and divide by two.

• Multiply the original amount by the new amount.

• Subtract the new amount from the original and divide by the new amount.

• Subtract the original amount from the new and divide by the original amount.

What is the first step in calculating the percent increase?

• Add the original and new amounts.

• Subtract the original amount from the new amount.

• Multiply the original amount by 100.

• Divide the new amount by the original amount.
