question 21

Multiple Choice

An open box is to be made from a square piece of cardboard,33 inches on a side,by cutting equal squares with sides of length x from the corners and turning up the sides (see figure below) .Determine the function,V,in terms of x,that represents the volume of the box.

• A) \(V ( x ) = - 4 x ^ { 3 } + 66 x ^ { 2 } - 33 x\)
• B) \(V ( x ) = - 2 x ^ { 3 } + 33 x ^ { 2 }\)
• C) \(V ( x ) = 4 x ^ { 3 } - 132 x ^ { 2 } + 1089 x\)
• D) \(V ( x ) = - 4 x ^ { 3 } + 66 x ^ { 2 }\)
• E) \(V ( x ) = 4 x ^ { 3 } - 66 x ^ { 2 } + 33 x\)
