16.) Find the volume of the square pyramid shown. Round your answer to the nearest whole number.
my answer: 6000 ft^3. Is that correct?
17.) 17.) A rectangular pyramid fits exactly on top of a rectangular prism. The prism has a length of 24 cm, a width of 3cm, and a height of 12cm. The pyramid has a height of 21 cm. Find the volume of the composite space figure.
my answer: 1308cm^3. Is that correct?

wheres your "square pyramid shown" ?

- anonymous

Everything that needs to be said is all there.

- anonymous

Why would you ask me a question and then leave?

- wolf1728

You need the height, the length of a side.....

- anonymous

you are asking 16 or 17?

- anonymous

and dont worry about people leaving, theres a notification when anyone says anything and they may get back to it

- anonymous

((can i just say something off topic? We all are canines XD)

- anonymous

yea

- anonymous

(its funny to me)

- anonymous

ima shiba inu aka doge

- wolf1728

Well with a name like "wolf" that makes me a canine - a canis lupus actually.

- anonymous

lol ya xD

- anonymous

so is it safe to assume that I am inccorect then?

- wolf1728

Are you asking question 16 or 17?

- anonymous

Both. But 16 first.

- wolf1728

we need the height, length of the sides...

- anonymous

Thats all the information they gave me.

- anonymous

no pictures?

- anonymous

they said shown!

- wolf1728

How did you calculate 6,000 cubic feet?

- anonymous

oh shoot! I am so sorry guys, I honestly thought that there was none and----its late.

- anonymous

hold on for one quick second.

- anonymous

16. http://assets.openstudy.com/updates/attachments/55bff878e4b03325500374c7-lollygirl217-1438658017694-as.jpg

- anonymous

16 is correct

- anonymous

Alright thank you.

- anonymous

17 is a little weird

- wolf1728

Height is 20 feet
volume = l*w*h / 3
volume = 30*30*20
volume = 18,000

- anonymous

you forgot to divide by 3?

- anonymous

correction: 1368 cm^3....unless i am still wrong

- wolf1728

saseal - yeah you're right :-(

- anonymous

the trick with 17 is finding the triangle area of the prism

- anonymous

wait...its going to end up remaining in the thousands right?

- anonymous

or perhaps it will go down to the hundreds...

- anonymous

i dont know yet lemme draw it out for you...theres 2 options for you to try|dw:1438667961880:dw|

- anonymous

both of this options will get you different answers

- anonymous

792 cm^2.

- anonymous

no?

- wolf1728

What do they mean by the "composite space figure"?

- anonymous

2,376 cm^3 or 4032 cm^3

- anonymous

Either of those can be correct

- anonymous

your pyramid volume is 288

- anonymous

huh...im lost. Im going to go with 2376 cm^3 as the final answer!

- anonymous

the question is actually asking you to find the volume of prism+pyramid

- wolf1728

That's what I thought when they said "composite figure".

- anonymous

ikr they like testing english with mathematics

- anonymous

I did it wrong again then...

- anonymous

welp!

- anonymous

refer to the figure i draw, even though my drawing sucks

- anonymous

okay, i shall.

- anonymous

4032 cm^3 BOOM

- anonymous

Thats it sonny~~

- anonymous

mcq stuff?

- wolf1728

Okay!!!

- anonymous

: <

- anonymous

damn lucky people getting multiple choice questions

- anonymous

lol~~
