The missing value in the dimensions of a rectangular prism having a volume of 50 5/8 cubic inches, length 5 inches, and width 214 inches, is found by dividing the volume by the product of length and width. On calculating, it is found to be approximately 1/7 inches.
The volume of a rectangular prism is found by multiplying the length, width, and height together. Here, you are given the total volume (50 5/8 cubic inches) and two of the dimensions (length is 5 inches and width is 214 inches). Therefore, the missing value is the height. To find this, you should divide the total volume by the length and the width.
So, Height = Volume / (Length x Width) = (50 5/8) / (5 x 214) = 81/ 14, which gives approximately 1/7 inches. Hence, none of the options (A, B, C, D) is correct.

What is a Sphere?
A sphere has a spherical, symmetrical shape. It is a three-dimensional solid with equal distances between each surface point and the center. On the basis of its radius, it has a surface area and a volume. There are no faces, corners, or edges on it.
The volume of a sphere is given by the formula
Volume of Sphere = ( 4/3 )πr³
where r is the radius of the sphere
Given data ,
Let the total cost of the liquid in the spherical tank be = A
Let the radius of the spherical tank be = R
The value of R = 6 yards
Now the cost of the liquid in the tank per cubic yard = $ 7.50
And ,
The volume of spherical tank = ( 4/3 )πR³
Substituting the values in the equation , we get
The volume of spherical tank = ( 4/3 ) x 3.14 x ( 6 )³
The volume of spherical tank = 25.12 x 6 x 6 x 6
The volume of spherical tank = 904.32 yards³
Now ,
The total cost of the liquid inside the spherical tank A = cost of the liquid in the tank per cubic yard x volume of spherical tank
Substituting the values in the equation , we get
The total cost of the liquid inside the spherical tank A = 7.50 x 904.32
The total cost of the liquid inside the spherical tank A = $ 6782.40
Therefore , the value of A is $ 6782.40
Hence , the volume of sphere is 904.32 yards³ and the cost of the liquid inside the tank is $ 6782.40
