Answer:
4) 216
5) 216%
6) It's just like the bird's eye view of the tank, exept it's 2d.
Step by step solutions:
4) Draw a cube. Draw another cube but smaller. Label sides of the big cube 6x and the small cube x. Find the volume of each, which are 216x^3 and x^3. Divide (216x^3)/(x^3) and you get 216 times.
5) It wants percentage of big over small, so redraw the diagrams from #4 and instead of x, set x as 2. So the big sides are 12 and the small sides are 2. But you should write the sides as 2*6 and 2. Then, you calculate the volumes: 12^3 = 1728 and 2^3 = 8. Percentage of small tank over big tank would be 8/1728, but we want the opposite. We want something bigger than 1. So, we take the reciprocal and we get 1728/8 % = 216%. All along, the times was the percentage.
6) Draw a cube and draw a cube or a rectangular prism, but be warned, we don't know exactly what shape it is. Hint: just do a cube with a little exagerated side length just in case teacher is bad. OK back to this. Then, draw a line through the cube/rectangle and you get a rectangle-like shape.

- Height & Area of the given parallelogram
✰
In right angled triangle ABE :
- Hypotenuse ( h ) = 8
- Perpendicular ( p ) = h [ height ]
- = 20°
Now , Using trigonometric ratio :
Plug the known values :
⟶
⟶
⟶
⟶
Now , We have :
- Base ( b ) = 15
- Height ( h ) = 2.72
Finding the area of a parallelogram whose base and height are 15 and 2.72 respectively :
❀
⟶
⟶
Hence , Our final answer :
