Answer 1

I'm the wrong person to ask lol I hate word problems.

Answer 2

I don't know, sorry, maybe you can help me @JazzyLuvsU123

Answer 3

Start by calculating the volume of the box. Then, calculate the volume of each block. You might be able to take it from there. :)

Answer 4

im in 7th grade what do u mean by calculate @jvatsim

Answer 5

I mean do you know the formula for volume?

Answer 6

Cube side3
Rectangular Prism side1 × side2 × side3
Sphere (4/3) × pi × radius3
Ellipsoid (4/3) × pi × radius1 × radius2 × radius3
Cylinder pi × radius2 × height
Cone (1/3) × pi × radius2 × height
Pyramid (1/3) × (base area) × height
Torus (1/4) × pi2 × (r1 + r2) × (r1 - r2)2

Answer 7

OK, great, looks like you have a boat load of formulas there! :) The question is which one do you think is used for blocks and boxes?

Answer 8

cube side 3

Answer 9

or rectangular prism side1 x side2 x side3

Answer 10

that's right, it's the second one because the blocks and the box have different size lengths.

Answer 11

kk I can try im so tired right now grrr

Answer 12

yeah, math can put you to sleep even when you're awake! :)

Answer 13

so 3x2x1=6 right !

Answer 14

good, that's the volume of each block

Answer 15

how about for the box?

Answer 16

would I times or divide for the box or same fomula ?

Answer 17

just use the same formula. :)

Answer 18

we're going to divide later on though... so don't get ahead of yourself. :)

Answer 19

18x10x3=540? right

Answer 20

@jtvatsim

Answer 21

yes, that is correct! Alright, we are ready for the final step.

Answer 22

The box can hold 540 "volumes" and each block is 6 "volumes" so you just need to divide to see how many blocks will fit.

Answer 23

divide 540/6 right ?

Answer 24

yep, otherwise you would have a fraction of blocks (and that doesn't make sense) :)

Answer 25

90 is my answer right !!!!

Answer 26

Yahoo! Good job!

Answer 27

thanks cause 9x6=54 so 90x6=540!!

Answer 28

nice math reasoning, don't even need a calculator for that. :)

Answer 29

nope

Answer 30

thans for ur help u earned a medal I have other problems coming up so be ready for more medals ;)

Answer 31

Alright, I'll be on for a bit longer, but if I'm not around, there's plenty of math gurus around here. :)
