Question

Carla has 1 gallon of paint. She is going to pour it into a paint tray that measures 10 inches wide, 10 inches long, and 7 cm deep.

(1 gallon = 231 in3, 1 inch = 2.54 cm)

Which of the following scenarios will happen?

The paint will not fill the tray by 44.59 in3.

The paint will not fill the tray by 469 cm3.

The paint will fill the tray exactly.

The paint will overfill the tray by 44.59 in3. @brookew41

Answer 1

Okay so first we need to find the volume of the tray in terms of cubic inches which they refer to as in^3.

Volume is the length multiplied by the width multiplied by the height. So we need to convert the height (7cm deep) into inches first.

Answer 2

won't it over flow

Answer 3

so 7x3

Answer 4

No, theres 1 inch in ever 2.54 cm... So 7 divided by 2.54?

Answer 5

2.7755905512

Answer 6

3

Answer 7

2.75*

Answer 8

Close... I'm getting 2.75590. We can't round yet though.

Multiply 2.75590 by the length and width which are both ten... what do you have now?

Answer 9

27.559

Answer 10

thats times length, now you have to multiply by the width which is 10 again

Answer 11

275.59

Answer 12

Good so we have the volume of the tray. now
If there is 275.59 inches cubed in the tray
The one gallon paint uses 231 inches cubed
What is the end result?

Answer 13

it will fill exact

Answer 14

How do you figure? 275.59 is bigger than the 231 cubic inches that the paint will fill.
Only 231/275.59 will be used... So it won't be filled. All you have to do is subtract 231 from 275.59

Answer 15

did i get it wrong :(

Answer 16

-44.59

Answer 17

275.59-231

Answer 18

so its positive 44.59

Answer 19

will it fill or over fill @brookew41

Answer 20

If there is 44.59 cubic inches left in the tray, then it is not filled right?

Answer 21

yes

Answer 22

So what answer is it? A or D? read carefully.

Answer 23

its A
