Note: <em>As you have not added the drawing. So, I assume the total number of two-inch cubes are stacked are FIVE. So, I will explain based on that assumption which anyways will clear your concept.</em>

Answer:

The total surface are will be: \boxed{120\:\:sq.in}

Step-by-step explanation:

As we know that

  • A cube contains 6 faces of equal area.

So, the total surface area of the cube is equal to 6 multiplied by the area of one of the faces.

As the edge of the cube = 2 inches

So, the area of one of the faces is:

                                                       2\times 2=4\:\:sq.in

Thus, the total area of the cube is:

                                                      6\times \:4=24\:\:sq.in

Assuming there are total 5 cubes which are stacked, so the total surface are will:

           24\times 5=120\:\:sq.in

Therefore, the total surface are will be: \boxed{120\:\:sq.in}

Answer:

The answer is D.) 120 sq.in

Step-by-step explanation:

Count the faces that show, multiply the faces by the area of each square. There area 30 sides/faces showing and the area of each square is 4, so 30 x 4 = 120 square inches.

117 Mr. Turtle, Mrs. Squirrel and Ms. Pigeon work at the Magic Forest's post office. Mr. Turtle can
insens350 [35]

Using proportions, it is found that the same job will take Mrs. Squirrel 6 hours.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The times are given as follows:

  • Mrs. Squirrel: x.
  • Mr. Turtle: 3 days.
  • Mr. Pigeon: 30 minutes = Half an hour = 1/48 day.

The ratios are as follows:

Turtle/Squirrel = Squirrel/Pigeon.

Hence:

\frac{3}{x} = \frac{x}{\frac{1}{48}}

x^2 = \frac{3}{48}

x^2 = \frac{1}{16}

x = \sqrt{\frac{1}{16}}

x = 1/4.

It takes 1/4 of a day for Mrs. Squirrel to do the job, hence 1/4 x 24 hours = 6 hours.

8. Let ABCD be a parallelogram with A on top left, B on top right, D on bottom left and C on the bottom right. Prove that opposi
AVprozaik [17]

Answer:

Step-by-step explanation:

A parallelogram is a quadrilateral with four sides.

Given parallelogram ABCD, to prove that opposite sides of the parallelogram are congruent.

Join D to B, the diagonal of the parallelogram which is also a traversal.

So that;

    <ABD = <BDC (alternate angle property)

    <BAC = <ACD (alternate angle property)

Also, diagonals;

      /AC/ = /BD/ (reflexive property)

Then;

      ΔABD = ΔCBD (Angle-Side-Angle, ASA, property)

Thus;

     /AB/ ≅ /CD/ (corresponding sides of congruent triangles are congruent)

    /BC/ ≅ /AD/  (corresponding sides of congruent triangles are congruent)

Therefore, the opposite sides of the parallelogram ABCD are congruent.
