The volume of a solid right pyramid with a square base is v units3 and the length of the base edge is y units

Answer with explanation:

Volume of a solid right pyramid with a square base = V (units)³

                            -------------------------------------(1)

The Solid right pyramid will be in the shape of Cube.

Length of edge of Right Pyramid = y units

So,Volume of Right Pyramid which is in the shape of Cube

= (Side)³

=y³ (Units)³

   Equating (1) and (2)

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
