Describe the cross section of the rectangular prism ?
a)hexagon
b)trapezoid
c)triangle
d)square

Option: D is the correct answer.

The cross-section of the rectangular prism is:

                       D)   SQUARE.

From the figure we could clear;y observe that the slicing is done perpendicular to the base of the rectangular prism i.e. cuboid.

Hence, as the face to which the plane is parallel will be obtained on this slicing.

As the face parallel to the plane that cuts the rectangular prism is in shape of a square.

                           Hence, we will obtain square.

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
