Question

You have to move 14 cubic yards of soil with 2 four cubic feet wheelbarrows. How many trips will it take?
43,560 sq. ft. = 1 acre

Answer 1

14*27/4

Answer 2

Assuming you can roll both wheelbarrows at once? That's a good trick.

Answer 3

^ lol

Answer 4

lol, yes...assuming that!

Answer 5

Haha okay, well let's start out by getting common units. 4 cubic feet is how many cubic yards?

Answer 6

i was thinking exactly the same as smoothman haha

Answer 7

why not the other way around 1 yd^3 = 27 ft^3

Answer 8

That is simpler.

Answer 9

what idiot measures his soil in yards and his wheelbarrow in feet?

Answer 10

It's just a math question, relax brother.

Answer 11

first answer is total number of trips
if you can move both at one time divide by 2 again

Answer 12

So you can move 8 cubic feet at a time, right? And you need to move 27 * 14 cubic feet total.

Answer 13

lol why does it tell us that 43,560 sq. ft. = 1 acre?

Answer 14

Just to make the problem that more inane, I suppose.

Answer 15

well thats 27*14/8 trips...

Answer 16

these are the choices: 75 / 85 / 95 / 105

Answer 17

ok so we cant roll em both at the same time, that 8 is now 4

Answer 18

giving us 95 trips where the last one has a half full wheelbarrow

Answer 19

Yeah, it must be.

Answer 20

yeah the first gives you 94.5

Answer 21

answer choices at beginning help greatly

Answer 22

sweet, now can you explain how you got to this answer for me?? I would really appreciate it "the duke"!

Answer 23

can any of the rest of us explain too? XD

Answer 24

Follow that, Lindsay? Each cubic yard is 27 cubic feet because 3 ft in a yard and 3^3=27. Then multiply by 14 to see that we need to move 378 cubic feet. We can move them 4 cubic feet at a time, so divide 378 by 4 to get 94.5. Obviousy we can't take half a trip, so we take 95.

Answer 25

THat'll do it! Have a good one y'all!

Answer 26

14 cubic yards is the total amount
you can move 4 cubic feet at a time
cubic yards and cubic feet are not equivalents so you must convert to a common unit
1 cubic yard is 3 feet by 3 feet by 3 feet which gives yoiu 27 cubic feet
so 14*27 gives you cubic feet
divide total cubic feet by number that can be moved at one time which is 4 cubic feet
thus the answer

Answer 27

You too.
