![]() In addition to being a polyhedron, a cube is also considered a parallelepiped because all its faces are formed by squares. It consists of 6 square faces, 12 sides and 8 vertices. A cube is a special case of a polyhedron.

You can prove that this critical value, x = 10, yields a MAX for volume by showing that the derivative goes from being + to - there. x = 10 The dims of the rectangular box of max volume are 10" x 10" x 5". So, we use the constraint, and solve for h to get h in terms of x: SA = x^2 + 4xh = 300 4xh = 300 - x^2 h =(300 - x^2) / (4x) Next, substitute that expression in for h in the volume equation: V = x^2 (300 - x^2) / (4x) Simplifying, V = 75x - (1/4)x^3 Take deriv, set = 0, solve: V' = 75 - (3/4)x^2 = 0. The problem with doing that for V = x^2h is that we have TWO variables. When you have a function in only one variable, it is relatively straightforward to take its derivative, set that deriv = 0, and solve to find the critical pt (either a max or a min). ![]() You are given a quantity to maximize or minimize (in this case the volume of the box), and you are given a constraint (in this case, the SA = 300 in^2). This is a very common question type for Calc AB, known as an optimization question. ![]() The dims of the rectangular box of max volume are 10" x 10" x 5". Next, substitute that expression in for h in the volume equation: So, we use the constraint, and solve for h to get h in terms of x:
