@Hero @TheSmartOne

OpenStudy (fortytherapper):

So they want you to fit the small cubes into the large one, right?

OpenStudy (niahloves):

yeah

OpenStudy (niahloves):

i guess

OpenStudy (anonymous):

Ok the answer you put there is wrong. There is a simple way to do this First, calculate the area of the prism Then, Calculate the area of the cube Then, if you divide the area of the large one into the are of the small one that gives you the answer

OpenStudy (niahloves):

I need help with that

OpenStudy (fortytherapper):

Can you go step by step on that, Brill? I see a different way of doing this

OpenStudy (niahloves):

@Brill

OpenStudy (anonymous):

Sorry first of all I meant VOLUME not area I apologize

OpenStudy (anonymous):

So the volume of the larger prism is 4.5*5*3.75 The volume of the smaller cube is .25*.25*.25 You then divide the 2 for the number of cubes

OpenStudy (niahloves):

So 1.4.5*5*3.75=84.375 And .25*.25*.25=0.015625

OpenStudy (niahloves):

@Brill

OpenStudy (fortytherapper):

Yep, then do like Brill said. Divide 84.375 ----- 0.015625

OpenStudy (niahloves):

I got 5400

OpenStudy (niahloves):

@FortyTheRapper @Brill

OpenStudy (fortytherapper):

Nice answer

OpenStudy (anonymous):

Yup

OpenStudy (niahloves):

Can you help me on more?

OpenStudy (anonymous):

Sure

OpenStudy (niahloves):

James has a board that is 3/4 foot long. He wants to cut the board into pieces that are each 1/8 foot long. Which an equation represents how James can find the number of pieces he can cut from the board? A. 1/8 + 3/4 = 7/8 B. 3/4 ÷ 1/8 = 6 C. 1/8 x 3/4 = 3/32 D. 1/8 ÷ 3/4 = 1/6

OpenStudy (anonymous):

So you have a whole, and then you're dividing it into parts of a specific size, does that sound like a similar function to you?

OpenStudy (niahloves):

nope

OpenStudy (anonymous):

By function I mean addition, subtraction, multiplication, and division

OpenStudy (niahloves):

oh yeah

OpenStudy (anonymous):

Which one is it?

OpenStudy (niahloves):

Times??

OpenStudy (anonymous):

You're taking a whole, and SPLITTING it into smaller pieces

OpenStudy (anonymous):

What is a synonym of splitting?

OpenStudy (niahloves):

oh Dividing

OpenStudy (anonymous):

Yup only one of them has dividing and there is your answer :D

OpenStudy (anonymous):

Actually your dividing the bigger one so that is the first term

OpenStudy (anonymous):

There is the answer

OpenStudy (niahloves):

so B?

OpenStudy (anonymous):

Yes

OpenStudy (niahloves):

OpenStudy (anonymous):

SO what are the dimensions of the triangle? Base and height?
