How do you find the lateral surface of a triangular prism
The lateral area [L] of a right prism with base perimeter [P] and height [h] is L=Ph.
Is electricity the same as electric light
Electricity is not the same as electric light. Electricity is
the flow of electrons from one atom to the next. As electrons
travel through the filament of a light bulb the resistance of the
filament opposes the flow of current, which creates heat. The
filament will heat up so much that it produces a visible light.
What is a blackbody radiator
A blackbody radiator, also known as a cavity radiator, is an
object or system which absorbs all radiation. It then re-radiates
the energy which is characteristic of the radiating system.
What is the special name for the segment that connects the center of a regular polygon to an outer edge to form the height of a triangle
Which polyhedron has more faces than a tetrahedron but fewer faces than an octahedron
Which of the following does not have triangular faces
dodecahedron
Hexahedron

A hexahedron is a prism whose base is a
The dodecahedron can be constructed from the repetitive folding of
All prisms are Platonic solids
What is the surface area of the cube below
There is no specific cube size mentioned here, however; the
formula to find size of the cube is 6a2 (square). Thus if the side
is 8", the surface area would be 6 x 8 x 6 = 384.
Is a cylinder a platonic solid
No. All the faces of a Platonic solid are identical regular
polygons.
Is it true that to find the surface area of a three dimensional figure you must find the area of each of its faces and then add them together
TRUE: To find the surface area of a three dimensional figure, you must find the area of each of its faces and then add them together.
Consider a regular pyramid where p is the perimeter of the base s is the slant height BA is the base area and LA is the lateral area What is a valid formula for the surface area
What platonic solids is also a cone
You could classify a regular tetrahedron, which is a platonic
sold, as a cone.
The horizontal cross sectional shapes of the cone are all congruent except for the vertex
What is a solid consisting of a polygon a point not in the same plane as the polygon and all points between them
Which can be constructed from polygons alone
More complicated polygons.
What is define the property of letting light pass through something
refraction and diffraction
refraction is when light passes through it bends but diffraction
is that light finds an opening to pass through while other waves
bounce off
What is the surface area of the rectangular prism below 8 8 19
There is no rectangular prism below 8 8 19.
Which of the following choices describe the bases of a cylinder A polygons B Discs C Parallel D Congruent
A cylinder has parallel discs bases that are congruent in
size.
Are The Shapes Of The Horizontal Cross-sections Of The Cylinder Below Are All Discs Of The Same Radius.
What following figures have 12 edges
A cuboid or a cube has 12 edges, 6 faces and 8 vertices
Which of tge following have at least two congruent parallel bases
What terms correctly describe the object below
solid, polyhedron, and prism for the block looking thing
Which of the following are not polyhedrons
