☆☆☆☆☆The lateral area [L] of a right prism with base perimeter [P] and height [h] is L=Ph.
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.
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.

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.
No. All the faces of a Platonic solid are identical regular polygons.
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.
SA=BA+LA
SA=BA+1/2ps
You could classify a regular tetrahedron, which is a platonic sold, as a cone.
False
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
There is no rectangular prism below 8 8 19.
A cylinder has parallel discs bases that are congruent in size.
True
A cuboid or a cube has 12 edges, 6 faces and 8 vertices
