Answer:
Uh
Step-by-step explanation:
With what ??? no picture
Here's the solution,
the volume of the given figure is :
=》

volume of pyramid :
=》

=》

=》

=》

volume of pyramid = 40 cm³
now, volume of rectangular prism :
=》

=》

=》

volume of rectangular prism = 40 cm³
volume of composite figure = 40 + 40
=》80 cm³
Answer:
A point and a line.
Further explanation:
Ray is part of the line with one endpoint. Ray is an endless straight path in one direction from a starting point, e.g., .
The arrow above the point shows the direction of the longitudinal beam. The length of the ray cannot be calculated.
Undefined terms are basic figure that is not defined in terms of other figures. The undefined terms (or primitive terms) in geometry are a point, line, and plane.
These key terms cannot be mathematically defined using other known words.
A point represents a location and has no dimension (size). It is labeled with a capital letter and a dot.
A line is an infinite number of points extending in opposite directions that have only one dimension. It has one dimension. It is a straight path and no thickness.
A plane is a flat surface that contains many points and lines. A plane extends infinitely in all four directions. It is two-dimensional. Three noncollinear points determine a plane, as there is exactly one plane that can go through these points.
The mean is 21. The median is 15. The mode is 15. The range is 16.
