Which of the following is the total number of whole boxes that measure 2.5 ft * 2.5 ft * 2.5 ft that can be stored in a room that measures 12 ft * 12 ft * 12 ft, if the size of the boxes cannot be altered?

A. 111

B. 105

C. 150

D. 120

Answer Explanation:

The number of boxes to fit the room is found as volume of the room divided by the volume of the box.

Number of boxes:

\(\frac{volume\ of\ the\ room}{volume\ of\ the\ box} = \frac{12ft\ *\\ 12ft\ *\ 12ft}{2.5ft\ *\ 2.5t\ *\ 2.5ft}\ =\ 110.592\)

The approximate number of boxes that can be stored in the room is approximately 111 square feet.

Therefore, the Correct Answer is A.

  • Q #2: Solve for z in the equation above.

    A. z=rwy+x

    B. z=rw+(y/x)

    C. z=y(x+rw)

    D. z=rw-(y/x)

    Answer Explanation

    We are asked to make z the subject of the formula.

    First, we subtract y/x from both sides of the equation

    Thus, the formula for finding the value of z is  .

  • Q #3: A circle has an area of 81π in2. Which of the following is the circumference of the circle in terms of pi ( π)?

    A. 4.5 π in

    B. 14 π in

    C. 18 π in

    D. 9 π in

    Answer Explanation

    we need to find the circumference of the circle from the given area.

    The first step is to find the radius of the circle using the given area. Let r be the radius of the circle, then:

    Substituting the value of area in the above equation becomes

    Dividing both sides by pi and taking square root on both sides yields

    Now, we know the radius of circle to be  9 in, the circumference of the circle becomes,

      in.
