Alec's Winnipeg Harvest Scribe Post

I learned that brown rice is healthier than white rice.I also learned that some people who volunteered in Winnipeg Harvest also experienced of not having food and been help by Winnipeg Harvest. They want to return the favor by working in Winnipeg Harvest whenever they had a free time . Winnipeg Harvest helped people by giving them food to eat. Stores liked Superstore and Costco helps Winnipeg harvest to supply food by giving them canned goods, milk and juiced.The top ten items that is needed in Winnipeg Harvest are:
  1. Canned fish and poultry.
  2. Canned fruit and vegetables (packed in own juiced)
  3. Canned stew, chili, brown beans
  4. Peanut Butter (light)
  5. Baby Food
  6. Whole grain pasta/ Whole wheat pasta
  7. Rice -Brown, Converted, Parboiled
  8. Canned Spaghetti or Tomatoes
  9. Cereal - High fiber, non-sugar coated
  10. Canned soup - Lentil, Pea, Vegetable
When I volunteered I was the one who scoop the rice and put it in a plastic.


Kevin's Winnipeg Harvest Scribe Post



What I learned from Winnipeg Harvest was that 823,856 people use food banks each month. Another thing I learned was that Manitoba has the one of the highest percentage of child food bank clients in Canada 46.6%! Winnipeg Harvest helps people that really can't find food to feed themselves or can't find the food to feed there children. Winnipeg Harvest gets there food from supermarkets such as Superstore, and others from the kind people that come to donate food. The top 10 items are as listed
  1. Canned fish and poultry.
  2. Canned fruit and vegetables
  3. Canned stew, chili, brown beans
  4. Peanut Butter (light)
  5. Baby Food
  6. Whole grain pasta/ Whole wheat pasta
  7. Rice (Brown, Converted, Parboiled)
  8. Canned Spaghetti or Tomatoes
  9. Cereal - High fiber, non-sugar coated
  10. Canned soup - Lentil, Pea, Vegetable
When I volunteered I remember i was the rice carrier as in I get the rice from the boxes and open them. Then I pour the rice into the containers for my group to package. It went from white rice to brown rice to parboiled/converted. We also noticed the the parboiled was lighter then white rice or brown rice.

Ryan's Volume Scribe Post

The questions I answered were numbers 4, 6, 8 in the homework book (pg. 80-81).
4. Calculate the volume of each rectangular prism.

a) l = 15 cm, w = 12 cm, h = 3 cm
v = l x w x h
v = 15 x 12 x 3
v = 180 x 3
v = 540cm3


















Jumbo
r = d/2
r = 20 / 2
r = 10cm

v = (πr2) x h
v = (3.14 x 102) x 40
v = (3.14 x 100) x 40
v = 314 x 40
v = 12, 560cm3

Popcorn Lover's
r = d/2
r = 30/2
r = 15cm

v = (πr^2) x h
v = (3.14 x 15^2) x 20
v = (3.14 x 225) x 20
v = 706.5 x 20
v = 14, 130cm^3

Popcorn Lover's has more space.


Full Circle
r = d/2
r = 1/2
r = 0.5m

v = (πr^2) x h
v = (3.14 x 0.5^2) x 10
v = (3.14 x 0.25) x 10
v = 0.785 x 10
v = 7.9m^3

"Hole" Circle
r = d/2
r = 0.8/2
r = 0.4m

v = (πr^2) x h
v = (3.14 x 0.4^2) x 10
v = (3.14 x 0.16) x 10
v = 0.5024 x 10
v = 5.1m^3

7.9 - 5.1 = 2.8m^3

Concrete volume is 2.8m^3.

Melanie's Volume Scribe Post

For my post, I will be answering the questions 4, 5, and 6 on the textbook work we did in class today. ( pages 258 - 261 )









*Sorry if some of the pictures are hard to see, just click it and it will appear bigger.

*Here is a link that will hopefully help those of you who don't understand how to find the volume of a rectangle / square.

If you guys don't
agree with my answers, have different answers or have any suggestions, just leave a comment! :)


Cylinder Volume and Volume Problems


v= π x r x r
v= 3.14 x 12cm x 12 cm
v= 452.16 cm2 x 15
v= 6782.4 cm3

6782.4 cm3 / 4= 1695.6 cm3


The volume of cheese taken from the block was 1695.6 cm3.
One assumption I made was that they cut 1/4 from the cheese.



r= d/2
r= 0.8m/2
r= 0.4 m

v=
π x r x r
v= 3.14 x 4cm x 4cm
v= 0.5024 cm2 x 10cm
v= 5.024 m3

r= d/2
r= 1m/2
r= 0.5m

v= π x r x r
v= 3.14 x 0.5m x 0.5m
v= 0.785 m2 x 10m
v= 7.85 m3

7.85 m3 - 5.024 m3 = 2.826 m3

The volume of concrete required to make the culvert is 2.826 m3.

Here is my volume video:

Kristel's Volume Scribe Post

3. Determine the volume of each right prism or cylinder.

a) v= area of base x height
15 cm2 x 4 cm
60 cm3

b) v= area of base x height
18 cm2 x 12 cm
216 cm3

c) v= area of base x height
96 cm2 x 20 cm
1920 cm3


9. How many ways can you build a rectangular prism from 16 centimeter cubes? Use diagrams or centimeter cubes to show your designs.

You can build 4 designs:

1 - L = 16 cm, W = 1 cm, H = 1 cm

2 - L = 4 cm, W = 2 cm, H = 2 cm

3 - L = 8 cm, W = 1 cm, H = 2 cm

4 - L = 4 cm, W = 1 cm, H = 4 cm


11. José is having vegetable soup. The area of the base of the soup can is 10.4 cm2, and the height is 10 cm. When José opens the can, he sees that the soup comes up to a height of only 9 cm. What volume of soup is in the can?

v = Area of base x height
10. 4 cm2 x 9 cm
93.60 cm3


15. The International Space Station is shaped like a cylinder that has a cross-sectional area of 615 m2 and a length of 44.5 m. The living space for the astronauts is 425 m3. What percent of the volume of the space station is used for living?

I had trouble figuring out things question. Please leave a comment and help explain to me how to figure it out!

Volume

Linear measurement is measuring a line with a ruler.

There are different units of measurement and some examples are centimeters, milimeters, and meters.

Area measurement is measuring an area with square units.

Volume measurement is measuring an area in cubic units.

If your measuring volume and it is a liquid, remember that 1cm3=1ml

The definition of volume- The amount of space an object occupies.

The formula for finding volume is area of base x height

The base is any face that shows the named face of the prism.

The height is the perpendicular distance between the two bases of a prism or cylinder.


Rectangular Prism


Area of base x height

l x w =a
5 x 6
30cm2=a
30cm2 x 10cm = a
V= 300cm3

Triangular Prism
