3 Dimensional Geometry Flashcards
A 3 dimensional shape that has width, height and depth is called what?
Solid figure
A solid figure whose ends (bases) are the same shape and are parallel to one another with rectangular sides connecting them is called what?
Prism
A solid figure whose base is a polygon and whose sides are triangles that meet at the top called the apex is called what?
Pyramid
The corners of a solid figure or where the lines or edges meet on a solid figure are called what?
Vertices
Where the faces of a solid figure meet (usually line segments, but not always) are called what?
Edges
The flat surfaces (can be curved) of a solid figure are called what?
Faces
The amount of space inside a 3 dimensional figure is called what?
Volume
The sum of the area of all the faces of a 3 dimensional figure is called what?
Surface area
What is the formula for calculating the volume of a rectangular prism?
V = L x W x H
Where L is length
W is width
H is height
What is the formula for calculating the volume of a cube?
V = S x S x S
Where is is the measure of the side
What is the formula for calculating the volume of a prism?
V = B x H
Where B is the area of the base of the prism
H is the height of the prism (which is the distance between the bases)
What is the formula for calculating the surface area of a prism?
Surface Area = 2 x area of the base + perimeter x height
What is the formula for calculating the surface area of a rectangular prism?
Surface area of rectangular prism = 2LW + 2LH + 2WH
Where L is length
W is width
H is height
What is the formula for calculating the surface area of a cube?
Surface area of a cube = 6 x S x S
Where S is the measure of a side
A prism whose bases or ends are circles is called what?
Cylinder
