1. PRISM AND SPECIAL PRISM …mathematic presentation

2. PRISM about prism: 3D geometric figure faces, vertex, edge = based on the type of the prism kinds of prism:  square prism/cube  rectangular prism  triangular prism etcetc

3. definition of square prism/cube square prism/cube is a three dimensional geometric figure with all sides made of squares—called faces. this presentation describe about cube as a prism and cylinder as a special prism, and just describe a little about rectangular prism… …next slide will describe more about cube: side, vertex, edge, volume, surface area, and diagonal formula C U E B

4. cube description: 3D geometric figure all sides are same all sides made of square—called faces side

5. cube’s surface area formula surface area = the sum of areas of all the face = Q : find the cube surface area if the edge is A : surface area surface area

6. cube’s volume formula V = Volume sa = side area s = length of edge Sa = Surface area e.g: 1) V = s 3 = 7 3 = 343 cm 2 2) volume

7. cube’s faces, spaces, planes diagonal  cube has 12 faces diagonal formula : the fact :  cube has 4 spaces diagonal formula : the fact :  cube has 6 planes diagonal formula : the fact :

8. definition of rectangular prism rectangular prism is a three dimensional figure that has two same sides and other four same sides. the figure is like cube, but not all sides are the same.

9. rectangular prism’s surface area formula Q:Sa = 426 cm 2 h = 12 cm w = 9 cm t = ? A:A: surface area

10. rectangular prism’s volume formula Q:V= 9000 cm 3 h= 10 cm w= 15 cm t= ? A: 9000= 10 x 15 x t 9000= 150 x t 150t= 9000 t= 60 cm volume

11. rectangular prism’s faces, spaces, planes diagonal  to find the faces, spaces, planes diagonal for rectangular prism is same as cube. but, to find the faces and spaces for rectangular prism, find it with Pythagoras theory—because not all sides are same. this is the basic formula :  to find the planes diagonal for rectangular prism, the formula is same as to find the area of rectangle. this is the basic formula : h x w

12. SPECIAL PRISM for special prism, we will describe about cylinder—circle prism.

13. definition of cylinder cylinder/circle prism is a three dimensional geometric figure that has two circle sides and a side who covers the figure around that two circles C y l i n r E D

14. cylinder description 3D figure has 2 same-circle-side and one rectangular cover has no vertex sidecover

15. cylinder’s surface area formula surface area 1) cover area = 2) circle side area = 3) perfect surface area (with two circle sides) = 4) imperfect surface area (without one circle side) =

16. cylinder’s volume formula volume 1)circle area = 2)volume = one circle side area x t = 3)d = 2r 4)r = ½ d 5)volume =

17. example : volume Q:d= 7 cm t = 14 cm V= ?V= ? A:V=A:V= = = =462 cm 3 vo lu me
