Answer:
The correct option is option number 4. Parallel lines are defined as lines that never have one point in common.
Step-by-step explanation:
Parallel lines: Parallel lines are the lines that will never cross each other. As they never meet, so they won't have a common point.
On the other hand, the other options are incorrect. This is because,
Perpendicular lines: Perpendicular lines are the lines that make 90 degrees angle with each other.
Skew lines: Skew lines are the lines that are not present on the same plane.
Coplanar lines: Any lines which are known to occur on the same plane are termed as coplanar lines.
5 equals 5/1. Simple as that.
Answer:
The surface area of the cuboid is 648 m^2
Step-by-step explanation:
What we have here is cuboidal in outlook
By using the formula for the surface area of a cuboid, we can get the surface area of the shape
mathematically, we have the surface area of a cuboid as follows;
2(lb + lh + bh)
where l is the length, b is the breadth (width) and h is the height
We can have the length as 9 m, the width as 9 m and the height as 13.5 m
Substituting these values, we have the surface area of the cuboid as;
A = 2(9(9) + 9(13.5) + 9(13.5))
A = 2(81 + 243)
A= 2(324)
A = 648 m^2
