The net of the cuboid
A cuboid has 6 faces.
The dimension of these faces are:
Length and Width; Length and Height;
Length and Width; Length and Height;
Width and Height; Width and Height;
This means that the faces will have the following dimensions:
6cm by 3cm; 6cm by 2cm
6cm by 3cm; 6cm by 2cm
3cm by 2cm; 3cm by 2 cm
Taking into account the above measurements and dimensions, you draw 6 faces, then join similar sides lengths.

Answer:

Step-by-step explanation:
Hello, please consider the following.
We can read from the graph that the vertex is (1,-4) , it means that the equation is, a being a real number.

And the point (0,-1) is on the graph so we can write.

So the equation is.

Hope this helps.
Do not hesitate if you need further explanation.
Thank you

-intercepts occur at points

, so it follows that setting

and solving for

will give you the

-coordinate of an intercept.

So the two intercepts are

and

. For values of

between the two intercepts, say at

, you have

, which means the bounded region lies above the

-axis.
The area of the bounded region is then given explicitly by the definite integral

Barring that (given your "no calc explanations allowed" caveat), the best you can do is to approximate the area of the region with basic shapes.
