What is the lateral area of a rectangular pyramid?
Find th elateral area of a rectangular pyramid having height 9 , base lenght 6 and base width 7
Is it true that the height of a regular pyramid is the height of a lateral face?
No, it is not true that the height of a regular pyramid is the height of a lateral face. The height of a regular pyramid is defined as the perpendicular distance from the apex (top vertex) to the base. In contrast, the height of a lateral face (triangular face) is the perpendicular distance from the apex to the base of that triangular face, which is not necessarily the same as the pyramid's overall height.
How many perpendicular lines has a square base pyramid got?
A square base pyramid has 8 perpendicular lines. These include the 4 edges of the square base perpendicular to each other and the 4 edges connecting the apex of the pyramid to each vertex of the base, which are also perpendicular to the base.
What happens to the lateral sides of a pyramid when the height of the pyramid is increased and the size of the base is decreased?
The lateral sides get taller and narrower. (:
Is the lateral edge of a pyramid is also its slant height?
No, the slant height is the from the top vertex to the base of the base of the pyramid, it forms a 90 degree angle with the base and slant height. The lateral edge is literally the lateral (side) edge.
How they called the pyramid is perpendicular distance between the vertex and bases?
The perpendicular distance between the vertex of a pyramid and its base is called the "height" of the pyramid. This height is crucial for calculating the volume of the pyramid, which is given by the formula ( V = \frac{1}{3} \times \text{Base Area} \times \text{Height} ). The height is always measured at a right angle from the vertex to the base.
What is a prism that has lateral edges perpendicular to its base?
rectangular parallelepiped.. :)
How many lateral faces does a square pyramid have?
Lateral faces are the number of faces excluding the base. Since the square is the base, the other 4 sides will each be touching a lateral face to form a square pyramid (or it wont be a pyramid). So, there are 4.
What Has a base that is a polygon the lateral faces are triangle?
a pyramid
If the height increases what happens to the lateral sides of a pyramid when you decrease the size of the base?
The lateral sides of a pyramid are going to be more steep if the size of the base is decreased. The pyramid will not be stable enough to stand on its own.
How many planes of symmetry does a rectangular pyramid have?
Two.
A square base pyramid has no perpendicular edges?
Correct
Does a square based pyramid have no perpendicular edges?
It does: on its base.
