Concept of surface area of a cube - act ExampleWhen the screw is joined to the sides, all four edges can be glued at the same time. That is, the bottom counts as one seam. After the bottom and sides are assembled, the top leave behind be attached.Part 1 - The prerequisite skills necessary to complete this problem Guiding the students so that they can calculate how some sheets of plywood must be used and determine how many solid seams must be madeThe prerequisites for this task include recognition of the cube and acquaintance of its properties, and the concept of surface area in general. This in turn expects that the students have previously dealt with the concept of the square and flat area in earlier classes so that they can now grasp the concept of the surface area of the cube. The skills required are the ability to measure in feet, derive formulae, and perform simple attachment and multiplication calculations related to working out areas, the time taken to complete a project , and the cost of materials. Besides this is the simple ability to compare quantities required at the final stage. They must also be familiar with the concept of 3 dimensions as found in objects around us that there is a tercet measure of depth/height besides length and breadth of two dimensional objects and drawings. And, appreciate how we can use (apparently) two-dimensional materials (the plywood sheets) to construct multidimensional objects (the cube shaped bin).Students should recognize that the number of pieces that need to be cut corresponds to the six faces of the cube. To account for the thickness of the sheets and allow the seams of edges to be made, four of these authoritys will have shorter dimensions than the 3 ft. x 3 ft. dimensions of the first two parts (from the first sheet for the top and bottom sides). Given the information contained in part 2 of the notes, the students should be aware how only 5 seams need to be made. The cube has 12 edges in total and two mee t to form a seam except that in some cases more
