A tetrahedron is a three-dimensional geometric shape with four triangular faces, six edges, and four vertices.
The volume of a tetrahedron can be calculated using the formula V = (1/3) * base area * height, where the base area is the area of one of the triangular faces and the height is the perpendicular distance from the base to the opposite vertex.
No, the volume of a tetrahedron cannot be negative. It is a measure of physical space and therefore must have a positive value.
The units for measuring the volume of a tetrahedron depend on the units used for the base area and height. For example, if the base area is measured in square centimeters and the height is measured in centimeters, the volume will be in cubic centimeters.
The volume of a tetrahedron is not directly related to its surface area. However, the surface area can be used to calculate the length of the edges, which can then be used to find the height and base area needed to calculate the volume.
