Calculating space
Triangles and quadrilaterals
Area
space taken up by the space
Perimeter
distance around the outside of the shape
Area of rectangle
length * width
Area of triangle
1/2 x base x vertical height
Area of parallelogram
base * vertical height
Area of trapezium
1/2(a+b) * vertical height
Spilt composite shapes into triangles and quadrilaterals. Work out each area and add together. Only include outside edges when adding up perimeters
Volume of Cuboids and Prisms
Volume
area inside a 3D shape
Volume of cuboid
L x W x H
Volume of prism
A x L
Volume of cylinder
Pi x Radius^(2) x H
Surface area formulas
Surface area of sphere
pi4^(2)
Surface area of cone
pi x radius x length
Surface area of cylinder
2pi x radius x height + 2pi x radius^(2)
Surface area nets
surface area
Total area of all faces
Net
A 3D shape folded out
