A regular tetrahedron, with edges of length 1 units, has a total surface area of sqrt(3) square units.
Not necessarily. If all faces are equilateral triangles (all edges are equal length) then it is a regular polyhedron.
The surface area of a triangular pyramid (tetrahedron) can be calculated using the formula: ( \text{Surface Area} = \frac{\sqrt{3}}{2} a^2 + \frac{\sqrt{3}}{4} a^2 ), where ( a ) is the length of a side of the base triangle. For a regular tetrahedron, the formula simplifies to ( \text{Surface Area} = \sqrt{3} a^2 ). To find the total area, you would need to know the length of the side of the base triangle.
If the area of the base of the tetrahedron is A square units and the vertical height is h units, then the volume is V = 1/3*A*h cubic units. If the tetrahedron is regular, with sides of length of length s units, then V = sqrt(2)/12*s3 cubic units.
The ratios are "small to large".

the five regular (same side length and angle measure) solids- dodecahedron, tetrahedron, cube, octahedron, icosahedron
The ratios are "small to large".
given the length of a side as S, the volume is: SQRT(2)*S3/12 Where SQRT(2) is the square root of 2 (~1,414) and S3 is the length of a side cubed.
Surface area of the pyramid: 4*0.5*144*sin(60) = 249 square cm to 3 significant figures
A regular solid is a three-dimensional shape where all sides are equal in size and all angles are equal. The method for determining if a solid is regular involves checking that all sides are equal in length and all angles are equal in measure. Examples of regular solids include the cube and the tetrahedron.
The approximate length multiplied by the approximate width.
Perhaps you mean length of "night". Try asking the question again.
Specifications say: Standard/Regular (length) - 20.5 gallons Optional/Extended - 25.5 gallons Note: these are approximate.
The foam tetrahedron consists of four equilateral triangles connected along their sides, forming a pyramid-like shape with a triangular base and three triangular faces. Each face of the tetrahedron is an equilateral triangle, and the edges of the foam tetrahedron are all of equal length.
