lukebluefive · Answer

Volume of rectangular prism = length x width x height = 11 inches x 7 inches x 2 inches
Volume of cylinder = height x PI x radius^2 = 3 inches x 3.14 x (8/2)^2 inches
Volume of cube = side^3 = 5^3 inches

Sum all three together and you'll have your approximate answer.  Remember to round the cylinder's volume to the nearest integer before adding it to the others.
