Math 9 Midterm Review: Surface area of Multiple Shapes

Question #1:

The Hobbs family is planning to paint their entire house. Each can of paint covers 32m2 and costs $35.50. What does it cost to paint the entire house including the roof?

Interconnectedness:

Interconnectedness, the way things are connected to each other. Things can connect to each other in any way. Whether it’s spiritual, physical, emotional, anything! In the picture, it shows the connection between the public, community and people. I interpret it as how people make a community and make up the public. Without people, there would be no communities or public.

Another connection I could make would be to the water cycle. The public will be the clouds, the community will be the bodies of water and the people will be individual drops of water. In order to make up the clouds and bodies of water, it needs water which is the individual drops. It is all interconnected. Each drop of water is needed to make up the clouds and bodies of water, like lakes, the sea, oceans, etc.. Without the water, just like with the community, public and people example, there would be no clouds or any bodies of water.

In the image, it shows people gardening, a house with a solar panel, a windmill and lots more. The people gardening will make a good impact on the future because it’s natural and instead of using store bought fertilizer, they use animal droppings which do not have a negative impact on the environment because it’s natural. This won’t create any extra pollution. There is no car in the picture, but there is a bike which means that they bike where ever they can. Unlike cars, bikes don’t need to use gas to power it which means that bikes also reduce pollution because it doesn’t create any. The house uses solar power and wind power as its source of energy and they’re both renewable sources, unlike fossil fuels. If they this family or small community were to continue to be environmentally friendly like this, the world would not suffer as much ice melting or high sea level rises from the global warming, nor nearly as much pollution as we see today.

This related to work that we’ve done in our class because in the carbon cycle, it is about how energy is recycled and used. This family plants trees which increases the amount of oxygen that can be created. They don’t burn a lot of fossil fuels which decreases the amount of carbon dioxide in the air because, instead of non-renewable energy sources that create pollution as their main source, they use solar or wind energy. This way, there isn’t too much carbon dioxide in the air and as the plants take in that carbon dioxide to make it oxygen it is more controlled and it would create a sustainable planet for them to live on. However, not everyone lives like this but if everyone did, or the majority of the Earth’s population did, our planted would be able to sustain us for a longer period of time without as many environmental problems as we face today.
