Everything that needs to be said is all there.

Answer 9

Why would you ask me a question and then leave?

Answer 10

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

Answer 11

you are asking 16 or 17?

Answer 12

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

Answer 13

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

Both. But 16 first.

Answer 22

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

Answer 23

Thats all the information they gave me.

Answer 24

Answer 28

hold on for one quick second.

Answer 29

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

Answer 30

16 is correct

Answer 31

Alright thank you.

Answer 32

17 is a little weird

Answer 33

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

Answer 34

you forgot to divide by 3?

Answer 35

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

Answer 36

saseal - yeah you're right :-(

Answer 37

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

Answer 38

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

Answer 39

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

Answer 40

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

Answer 41

both of this options will get you different answers

Answer 42

792 cm^2.

Answer 43

no?

Answer 44

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

Answer 45

2,376 cm^3 or 4032 cm^3

Answer 46

Either of those can be correct

Answer 47

your pyramid volume is 288

Answer 48

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

Answer 49

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

Answer 50

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

Answer 51

ikr they like testing english with mathematics

Answer 52

I did it wrong again then...

Answer 53

welp!

Answer 54
