Maths Form 2 Chapter 6: 3-Dimensional Geometrical Shapes
Prism
Surface area =
(2 x area of triangle) + (3x area of reactangle)
Volume =
area of cross section x height
Characteristics
2 flat bases
Flat quadrilateral side
Uniform cross section
Square-shaped Pyramid
Surface area =
area of square + (4 x area of triangle)
Volume =
1/3 x base area x height
Characteristics
1 flat base
Other sides are triangular shaped
All apex triangle meet at apex
Cylinder
Surface area =
2πr² + 2πrh
Volume =
πr²h
Characteristics
2 circular bases which are congruent / parallel
1 curved surface
which combines both circular bases
Cone
Surface area =
πr² + πrs
Volume =
1/3 πr²h
Characteristics
1 circular base
1 curved surface
Sphere
No net
Surface area =
4πr²
Volume =
4/3 πr3
