Pyramid activityOnline version This activity consists of testing the basic concepts about pyramid, through problems and contexts of our daily life. by Leidy Munar 1 First: A pyramid in my collection (see image) has a square base measuring 5cm, and the side edge is 8cm. How high is the pyramid? a h=7,17m b h=8,2m c h=7,17cm d h=8,2cm 2 Second: Find the Total area of the roof of a hut that is shaped like a Pyramid (see image) whose base is square 3.5m and the height is 10 meters. a AT=83,3133m^2 b AT=73,3133cm^2 c AT=83,3133cm^2 d AT=73,3133m^2 3 Third: My mother among her collection has an orgonite pyramid (see image), whose capacity is 128 cm3, the area of its base is 16 cm2. What will its height be? a 18 cm b 24 cm c 16 cm d 14 cm 4 Four: Find the volume of a hut that is shaped like a Pyramid (see image) whose base is square 3.5m and the height is 10 meters. a V=83,6m^3 b V=83,6cm^3 c V=40,83cm^3 d V=40,83m^3 Feedback 1 1. In this question the basic concepts are tested, given their elements, using the Pythagorean theorem, the value is found. 2 2. The basic concepts are put to the test, given their elements, by means of the Pythagorean theorem, the value of the apothems is found, to later find the value of the lateral area, which are 4 triangles and then multiply it by 4 and add it to the area from the base. 3 3. Using the volume formula, we solve for h where in this way the height of the pyramid is found. 4 4. Through the clue in the question, the volume value is found by the value of the area of the base and is multiplied by the height and divided by 3.
