# Surface Area

### 3-Dimensional Shapes

TermDefinition
height the measurement of vertical distance
width the measurement or extent of something from side to side
depth the distance from the top or surface of something to its bottom
face the outside flat surface of an object
edge the line where two faces come together on a shape
base usually the bottom of a three-dimensional object (sometimes the top)
attributes different features of a shape
cylinder one of the most basic curvilinear geometric shapes
prisms solid objects with identical ends, flat faces, and the same cross section all along its length
cube three-dimensional solid object bounded by six square faces with three meeting at each vertex
cone a three-dimensional geometric shape that tapers smoothly from a flat base to a point called the vertex
pyramids three-dimensional figures that have a polygon for a base and have a single vertex that is not in the plane of the polygon base
vertex the point where all of the edges of a pyramid meet/the point of a cone
surface the curved outside (or face) of a cone or cylinder
surface area the sum of all the areas of the faces, bases, and surfaces of a three-dimensional shape
pentagon any five-sided polygon
triangle polygon with three edges and three vertices
square a plane figure with four equal straight sides and four right angles
parallelogram a flat shape with opposite sides parallel and equal in length
polyhedron a complex shape that is made up of many faces that have identical shapes
hexagon a polygon with six edges and six vertices
octagon a plane figure with eight straight sides and eight angles
circle a round plane figure whose boundary consists of points equidistance from a fixed point
area the size of a surface
radius the length of a line segment from a circle or sphere's center to its perimeter
slant height height of a triangle face
