surface area

• square area = s2
• rectangle area = l x w
• triangle area = base x height / 2
• circle area = pi r squared
• cylinder volume = (2 x pi x r2) + (pi x d x h)
• circumferance = 3.14xd or 3.14xr2
• net = when a 3D object is flattened out, the net is the same as the shape of the object
• face = the front view of the object, the side view of the object, the top view of the object
• edge = line that joins vertices together
• vertex = where two edges meet
• triangle surface area =( 3 x area of rectangles + area of triangles)
• rectangular prism formula = length x width x height
• circumferance form diameter = 3.14/diameter
