Question

Billy has 1 gallon of paint. He is going to pour it into a paint tray that measures 10 inches wide, 14 inches long, and 4 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 441 cm3.

The paint will not fill the tray by 10.53 in3.

The paint will fill the tray exactly.

The paint will overfill the tray by 10.53 in3.

Answer 1

Convert all measurements to the same (in or cm) then calculate the volume of the tray. (WxDxL). Compare it to the volume of the gallon.

Answer 2

You'll have to do it in inches and cms as both appear in your answers.

Answer 3

Or you could just do it in inches and if it doesn't fit with answers 2, 3 or 4 then the answer must be 1 :)

Answer 4

(1 cubic in) = (2,54)^3 cu. cm=16.387 cu. cm
Just a hint to avoid a common mistake.

Answer 5

Im So Confused.

Answer 6

You can do it, it is just arithmetic. Mostly multiplying.

Answer 7

I would first compute the volume of the tray and I would do that in cubic inches.
10" X 14" X (4/2.54) that would be:
10" X 14" x 1.5748" or 220.472 cubic inches. Do you follow so far with understanding?
The height that was given in cm (4 cm) was converted to inches and volume was obtained by multiplying width X lenght, X depth.

Answer 8

You can now see (or should see) that the gallon of paint which was given as 231 cu in is more than the tray can hold. You should now be abled to select the best answer. Good luck.

Answer 9

Ohhhhh Okay I See Now. Thank You.

Answer 10

Which one do you think is the best answer?

Answer 11

Since the tray volume is less than the paint volume, we know that the paint would fill the tray and have some left over, so we eliminate the first two choices. Agree?

Answer 12

so whats the answer?

Answer 13

Paint tray overload.....lol
