Unit 6 - Surface Area and Volume for Rectangular Prisms



Summary of Knowledge:
The goal of this investigation is to be able to create a net, be able to create a box, and create net with given bow or create a box with a given net.This is very important because it may help us in the future specially if we decide to become architects. The main key terms that appear in this section are Surface Area and The Volume of a rectangular prism.
Key V0cabulary:
cube: A three-dimensional shape with six identical square faces





8 vertice









  1. 12 edges




net: A net is a two-dimensional shape pattern that can be folded to form a three-dimensional shape.





rectangular prism: A prism with a top and a bottom that are congruent rectangles.





base: The face of the three-dimensional shape chosen to be the bottom face









Task Analysis:





Suface Area: first you must find the are of each face of the rectangular prism. Then you add them up and you have the surface area. You could also find the surface area by getting the area of the three distinct faces and then multiply them by two.





Volume:to find the volume of a rectangular prism yopu must multiply the dimensions.





The equation for finding the volume of a rectangular prism is (lxwxh)





Examples:





The volume of this box is 8 sinse the dimensions are 2x2x2 (lxwxh)





The surface are of this cube 12 since the dimension of an face is 2x2=4 sinse its a cube you multiply times 6 that equals 12.
