Answer:
You came to the right place.
let's crunch some numbers.
I don't have any work though. Sorry.
1. 63 cubic cm
2. 300 cubic in
3. 96 cubic m
4. 90 cubic mm
5. 186.2 cubic in
6. 97.2 cubic m
Answer:
D
Step-by-step explanation:
The question firs states that the points are moved three points upwards. This means that each point has an increase of the y value by three points.
This gives us the points (0,4), (4,3) and (4,-4)
Reflecting them across the y-axis, it means that their height will stay the same. but the x value will be on the other side of the x- axis.
This leaves us with the answer D.
Note that the first point stays the same because it is on the y-axis, it doesn't get reflected.
Hope this helps.
Part A:
In the purple writing, I found the height of the triangle using the Pythagorean theorem.
I think this is what the question is calling the "height of the box".
height of the box = 15 cm
Part B:
The amount of cardboard needed for the sides will be the lateral area of this prism.
lateral area = perimeter of triangle * height of prism
lateral area = (16 + 17 + 17) * 20
lateral area = 50 * 20
lateral area = 1,000 cm2
