Moritz bought an ottoman that is cube shaped with side lengths of 2 feet. Its lid is removable for storing blankets and pillows.
jeka57 [31]

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.

Step-by-step 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, <em><u>Volume's Unit</u></em> is in Cubic Feet. That statement is correct.

The lid is a square. The area is: A = 2*2 = 4 <u>square</u> 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.

Y = -x<br><br> What is is the constant of proportionality
Stels [109]

Hey!

------------------------------------------------

-x = -1

This statement shows that y equals -1. Since it doesn't show a table or word problem then we already know that the constant of proportionality is -1. Or if you just have the expression just divide the number by 1. -x/1 = -1!

------------------------------------------------

Thus, -1 is the constant of proportionality!

------------------------------------------------

Hope This Helped! Good Luck!
