<em>Greetings from Brasil...</em>

X = 2 liter container

Y = 3 liter container

the total of containers are:

X + Y = 400

the capacity of the containers is

2X + 3Y = 1100

Assembling the equation system

2X + 3Y = 1100

X + Y = 400       x(-2)

2X + 3Y = 1100

<u>-2X  -2Y = - 800    </u>

<h3>Y = 300</h3>

X + Y = 400    so

X + 300 = 400

X = 400 - 300

<h3>X = 100</h3>

----------------------------------------------------------

<em>BR:</em>

<em>Observe que:</em>

<em>1 vasilha de 2L = 1 × 2 = 2L</em>

<em>2 vasilhas de 2L = 2 × 2 = 4L</em>

<em>3 vasilhas de 2L = 3 × 2 = 6L</em>

<em>X vasilhas de 2L = X × 2 = 2X litros</em>

<em>.....</em>

<em>1 vasilha de 3L = 1 × 3 = 2L</em>

<em>2 vasilhas de 3L = 2 × 3 = 4L</em>

<em>3 vasilhas de 3L = 3 × 3 = 6L</em>

<em>X vasilhas de 3L = X × 3 = 3X litros</em>

<em>Logo 2X + 3Y = 1100</em>

<em>Existem X e Y vasilhas que num total sao 400, logo</em>

<em>X + Y = 400</em>

1. Calculate the volume of entire cube as if it was a solid rectangle:
Length x width x height=
20x16x12 = 3,940 cubic inches

2. Calculate the volume of the "missing"
Piece and subtract:
Length x width x height=
20x8x6 = 960 cubic inches
(notice you can find the height of the missing piece by subtracting 12-6)

So your answer is 3,940-960 = 2,980 cubic inches inside the steps
