Question

Elaine has 1 gallon of paint. She is going to pour it into a paint tray that measures 10 in wide 12 in long and 5 cm deep. ( 1 gallon=231 in^3, 1 inch=2.54cm)

Answer 1

b. The paint will not fill the tray by 5.22 in3.

Explanation:

The computation is shown below:

First we have to determine the volume of tray by using the following equation

`V = L * W * H`

Now transform this from dimensions to inches

Now putting the values,

`V = 10*12* (5*((1)/(2.54))) \\\\As\ 5 cm = 5 * ((1)/(2.54))`

the volume would be equivalent to the

236.22 inches^3

Now 1 gallon is 231 inches^3

So, the remaining would be

= 236.22 - 231

= 5.22^3

Therefore the correct option is b.

Hence, all the other options are wrong
