Asked by John

This question is based on the book "The Curious Incident of the Dog in the Night-time" by Mark Haddon.

What do you think makes a hero? How does Christoper fit your idea of a hero? He has been described by some readers as "a new kind of hero" or "an unlikely hero". How would you respond to these descriptions of Christopher? Is he different to a real hero?

Since I haven't read this, I really have no idea, but be sure to re-read the questions closely. "What do <b>you</b> think ... " "How does Christopher fit <b>your</b> idea ... " Etc.

There are lots of "you" words in these questions. This means that your teacher wants to know what YOU THINK. So ...

Make sure you are clear on what YOU THINK the word "hero" means:

Make sure you are clear on what YOU THINK the terms "a new kind of hero" and "an unlikely hero" mean.

You must be crystal clear in your own mind about the meanings of these words and phrases before you can begin to answer these questions.

You must also have read the book carefully, and probably even re-read the sections in which this character demonstrates being a "hero."

The reviews in the search results below may help, but probably not nearly as much as reading the book carefully and being clear on the meanings of the terms in the questions.

What is a rectangular prism?

A three-dimensional solid form with six faces, including rectangular bases, is called a rectangular prism. A rectangular prism also refers to a cuboid. A cuboid and a rectangular prism have the same cross-section.

Here, we have

Let the missing length be x cm.

The formula for the surface area of a rectangular prism is:

SA = 2lw + 2lh + 2wh

We are given that the height and width are both 9 cm, so we can substitute those values and simplify:

432 = 2(x)(9) + 2(x)(9) + 2(9)(9)

432 = 18x + 18x + 162

432 - 162 = 36x

270 = 36x

x = 270/36

x = 7.5

Hence, the missing length is 7.5 cm.

The missing length of the rectangular prism is 4 cm.

Sure. We know that the surface area of the rectangular prism is given by the formula SA = 2(lw + lh + wh), where l, w, and h are the length, width, and height of the prism respectively. We're given that the height and width are both 9 cm, so we can substitute these numbers into the formula to get:

432 = 2(l * 9 + 9 * h + l * h)

Simplify by factoring:

432 = 2(l + 9)(h + 9)

Divide both sides by 2:

216 = (l + 9)(h + 9)

To find l, we need to solve for it. We know that h = 9, so substitute this in:

216 = (l + 9)(9 + 9)

216 = (l + 9)(18)

Divide both sides by 18:

12 = l + 9

Subtract 9 from both sides:

3 = l

So the missing length of the rectangular prism is 3 cm.

The missing length of a rectangular prism with a surface area of 432 cm2, height and width of 9 cm each, is 7.5 cm. This can be found by solving the equation 432 = 2(x)(9) + 2(x)(9) + 2(9)(9) for x.

Correct.

The formula for the surface area of a triangular prism is:

S.A. = 1/2(l1 * w) + 1/2(l2 * w) + (l1 + l2) * h

which can also be written as

S.A. = 1/2(S1 + S2 + S3) * h

where S1, S2, and S3 are the three side lengths of the base triangle, l1 and l2 are the two perpendicular heights from the base to the opposite faces, w is the width of the base triangle, and h is the height of the prism.
