Question

Moritz bought an ottoman that is cube shaped with side lengths of 2 feet. Its lid is removable for storing blankets and pillows. There is a child safety bumper around its top edge.

Left, a cube. Right, a square labeled lid.

Which statements are true about the ottoman? Check all that apply.


The amount of storage for pillows and blankets is measured in cubic feet.

The child safety bumper is best measured using area.

The area of the lid is 4 feet.

The length of the child safety bumper equals the perimeter of the top of the ottoman, which is 8 feet.

The volume of the cube is 8 ft3.

Answer 1

Answer: Statements that are true are: ()The amount of storage for pillows and blankets is measured in cubic feet and ()The volume of the cube is 8 ft3.

Explanation: A cube is a box-shaped solid object that has 6 identical square faces. Volume is the amount of space a enclosed object occupies.

The volume of an ottoman is the amount of storage for pillows and blankets and since it's calculated, in this case, as:

V = length*width*depth, and the unit is in feet, Volume's Unit is in Cubic Feet. That statement is correct.

The lid is a square. The area is: A = 2*2 = 4 square ft, so this statement is incorrect.

The perimeter of the top is: P = 4*2 = 8 feet, but it's not the length of the child safety bumper, so this statement is false.

An ottoman is a cube of side lengths 2 feet, so its volume will be V=8ft3.

Therefore, the correct statements are:

• The amount of storage for pillows and blankets is mesured in cubic feet;
• The volume of the cube is 8ft3.
