Which solid has two rectangular bases and four lateral faces, each in the shape of a rectangle?
2 answers:
Answer with explanation:
The total number of faces that the solid has = Two rectangular bases + Four lateral faces
As , Opposite Rectangular bases are Congruent,as well as four Opposite Rectangular Lateral Faces are Congruent.
Drawing the shape on a piece of paper and trying to find which shape it resemble
It is Rectangular prism, which we can call Cuboid.
→A prism is a three dimensional solid, whose opposite base can be in the shape of any polygon and lateral faces are always Parallelogram.
Here opposite bases are rectangle and lateral faces are Parallelogram.

Answer with Step-by-step explanation:
We are given that an equivalence relation P on Z as
Let
if and only if
such that x-y=2k.
We have to show that how the reflexive property and symmetric property of an equivalence relations hold for P on Z.
We know that reflexive property
a is related to a by given relations.
If xPax then we get
Where k=0 and 0 belongs to integers.
Hence, the relation satisfied reflexive property.
Symmetric property :If a is related to b then b is related to b.
If x and y is related by the relation
where k is any integer
k belongs to integers.
Hence, relation satisfied symmetric property.
