Questions 18 and 19
Question:
18.Suki has 30 small linking cubes.
a)She wants to use 18 of them to make a large cube. Is this possible? Why or why not?
b)What number of linking cubes would she use to construct the largest cube she can possibly make?
Answer:
a)I say this is not possible because I think there is no whole number that could be cubed to be able to equal 18.
b)She would probably need to use 27 cubes to make the largest cube possible (3x3x3).
Question:
19.Melissa has three glass vases. She wants to use one as a decorative fish tank for Harvey the guppy. Which will give Harvey the most water to swim in.
Answer:
The volume of the one shaped as a cube is 343cm2.
The volume of the one shaped as a rectangular prism is 360cm2.
The volume of the one shaped as a triangular prism is 367.5cm3.
According to the volumes, the triangular prism would've the most water for Harvey the guppy to swim in.

Awesome job D.P! Your work is very organized and is clear to read. I like the videos you have put in, and also your pictures. I like the way you have important words highlighted with a lighter and different font colour. A heads up for next time is maybe you should add a video of yourself, that would be pretty cool, but your overall work and effort is great, keep it up!
ReplyDeleteGreat job Demvry!
