Homework Statement
The volume of a cube is 'v' cubic yards, and its surface area is 'a' square feet. If 'v' = 'a' what is the length in inches of each edge?
Homework Equations
volume of a cube = e^3
surface area of cube = 6e^2
The Attempt at a Solution
volume of a cube = 'v' cubic yards
= 'v' * 3 feet
= 'v' * 3 * 12 inches
= 36 'v' inches
surface area of a cube = 6 * e^2
'a' = 6 * e ^2
'v' = 6 * e^2
Now volume of cube = 36 * 6 * e ^2 inches
e^3 = 216 e^2 inches
e = 216 inches
But answer is not correct. Some body please guide me.
