Time to think… The length of is 10cm. The width is 8 cm. The height is 12 cm. What is my volume?
![Page 11: Picturing Polygons Review](https://reader036.fdocuments.net/reader036/viewer/2022062410/568161ab550346895dd1685e/html5/thumbnails/11.jpg)
Explanation The length of is 10cm. The width is 8 cm. The height is 12 cm. What is my volume?
L X W X H = 960 cubic cm

Time to think… Find the volume…
5 ft
10 ft*Width for entire objectIs 4 ft.
5 ft
15 ft

Explanation Find the volume…
5 ft
10 ft*Width for entire objectIs 4 ft.
10x4x5 = 200 15 x5x4 = 300
5 ft V=500!

Time to think… What type of angle is this?
![Page 15: Picturing Polygons Review](https://reader036.fdocuments.net/reader036/viewer/2022062410/568161ab550346895dd1685e/html5/thumbnails/15.jpg)
Time to think… What type of angle is this?
Obtuse… more than 90°
![Page 16: Picturing Polygons Review](https://reader036.fdocuments.net/reader036/viewer/2022062410/568161ab550346895dd1685e/html5/thumbnails/16.jpg)
Time to think… Mrs. Schuldt says a trapezoid is a polygon that
has exactly one set of parallel sides. Mrs. Nestor says a trapezoid is a polygon that
has at least one set of parallel sides. Which teacher is correct, according to the
hierarchy below?
![Page 17: Picturing Polygons Review](https://reader036.fdocuments.net/reader036/viewer/2022062410/568161ab550346895dd1685e/html5/thumbnails/17.jpg)
Explanation Mrs. Schuldt says a trapezoid is a polygon that
has exactly one set of parallel sides. Mrs. Nestor says a trapezoid is a polygon that
has at least one set of parallel sides. She’s right because Parallelograms have 2 sets of parallel sides.
Which teacher is correct, according to the hierarchy below?

Time to think… Which is not a unit cube that could be used to
find volume? A. 1 in x 1 in x 1 in B. 1 yd x 1 yd x 1 yd C. 12 in x 12 in x 12 in D. 2 in x 2 in x 2 in
![Page 19: Picturing Polygons Review](https://reader036.fdocuments.net/reader036/viewer/2022062410/568161ab550346895dd1685e/html5/thumbnails/19.jpg)
Time to think… Which is not a unit cube that could be used to
find volume? A. 1 in x 1 in x 1 in B. 1 yd x 1 yd x 1 yd C. 12 in x 12 in x 12 in D. 2 in x 2 in x 2 in – it must be a set unit of
measure- a foot, an inch, a meter, etc.

Time to think… What names describe the shapes below?
![Page 21: Picturing Polygons Review](https://reader036.fdocuments.net/reader036/viewer/2022062410/568161ab550346895dd1685e/html5/thumbnails/21.jpg)
Explanation… What names describe the shapes below?
Triangle, equilateral, isosceles Quadrilateral, Parallelogram, rectangle,
rhombus, square
![Page 22: Picturing Polygons Review](https://reader036.fdocuments.net/reader036/viewer/2022062410/568161ab550346895dd1685e/html5/thumbnails/22.jpg)
Explain… Why is a square a rectangle, but a
rectangle not a square?
![Page 23: Picturing Polygons Review](https://reader036.fdocuments.net/reader036/viewer/2022062410/568161ab550346895dd1685e/html5/thumbnails/23.jpg)
Explain… Why is a square a rectangle, but a
rectangle not a square? A square is a rectangle because it has two
pairs of congruent sides, two pairs of parallel sides, and four right angles. A rectangle is not a square because it does not have all 4 sides congruent.
