Determine the value of the x-coordinate of the vertical black line that
splits the trapezoidal area defined by x-axis, the red line whose
equation is y= (1/2)x +1 and the two blue lines at x=2 and x=4 into two
trapezoids such that the area of the left trapezoid = 1/2 the area of
the right trapezoid. Show a 3-decimal digit accuracy in the answer.

Here's a problem I recently worked on w/ a calculus student. Rotate the area defined by the two curves about the line y=2 and figure out the volume of the object. I find visualizing such things difficult. The idea here is to see the problem as summing a bunch of hollow cylinders (or "washers"). The volume of a cylinder is the area of the base times the height.

How to tile a square with 5 rectangles with edges in [1,10]

131. tile.html  tile.tc   permutation.py   permutation.c   edges.1b.py

What is the height (in cm) of a solid rectangular cube with base having a perimeter of 18 cm and which is made up of 42 square unit cubes (i.e. 1x1x1 cm^3)?

The "volume" of the cube = 42 = 2*7*3. If w,l,h stand for width, length, height, we get volume= w*l*h so volume/(w*l) = h. The perimeter is 2*(w+l)=18 so w+l=9 or w=9-l. volume/((9-l)*l) = 2*7*3/((9-l)*l). The only way the right hand side will be a whole number is if l = 2 which means h=3.
