a box with a square base is taller than it is wide. in order to send the box through the US mail, the height of the box and the
NemiM [27]

The given box has the shape of a <u>cuboid</u>, since its <em>height</em> is greater than its <em>width</em>. Thus, the <em>maximum volume</em> for such box is 11200 in^{3}.

The <u>volume</u> of an object is a measure of it <em>containing</em> capacity. Since the given box has a taller <em>height</em> than its <em>width</em>, then it has the shape of a <em>cuboid</em>. The<u> volume</u> of a cuboid is given as:

volume = length x width x height

            = area x height

Given that the <u>sum</u> of the <em>perimeter</em> of its base and its <em>height</em> is not more than 108 inches, we can say; let the sides of the <em>square</em> base be represented by l and its height by h.

Then;

4l + h = 108

Therefore, maximum volume for the box can be attained when l = 20 inches and h = 28 inches.

So that;

4(20) + 28 = 80 + 28

                 = 108 inches

Thus;

maximum volume = area of the square base x height

                        = 400 x 28

maximum volume = 11200 in^{3}

The <u>maximum</u> <u>volume</u> for such a box would be 11200 in^{3}.

OverLord2011 [107]

Answer:

A. x + 200 = 450

Step-by-step explanation:

Since clara deposited $200 into her savings account and it brought her account up to $450, to find the answer you would add "x" with 200 and you should get 450 which means x= 250. we can check our answer by solving : 450-200 and you should get 250 for your answer so the answer is

A x + 200 = 450

m_a_m_a [10]

Answer:

See below

Step-by-step explanation:

1 . Missing angle

Sum of interior angles in the triangle = 180°

  • 180° - (105° + 29°) = 36°

2. Angle 1

  • Angle 1 is exterior angle of the triangle
  • Angle 1 = 55° + 78° = 133°

3. Angle 2

  • Angle 2 = 180° - (55° = 78°) = 47°

4. The sum of exterior angle and adjacent interior angle equals 180°

If they are equal, then each will measure 180°/2 = 90°

So it is possible with the right triangle
