The surface area of the cuboid is 18X + 7.
Calculate X.
To determine the value of , we'll use the formula for the surface area of a cuboid:
The formula for the surface area of a cuboid is .
Given that , , and , we plug these values into the surface area formula:
We equate this expression to the given surface area:
By simplifying, we subtract from both sides:
Which simplifies to a contradiction, demonstrating that these conditions are not possible with the given figure.
Conclusively, the given surface area is not possible.
The given surface area is not possible.
A cuboid is shown below:
What is the surface area of the cuboid?
This is a mathematical contradiction! When you simplify and get an impossible statement like 40 = 7, it means the original problem conditions cannot exist in the real world.
Calculate the surface area using the cuboid formula . If this doesn't equal the given expression for any value of the unknown, the problem is impossible.
No! Once you've proven mathematically that the equation leads to a contradiction (like 40 = 7), no value of X can make it work. Trust the algebra!
In real life, every cuboid has a specific surface area based on its dimensions. If someone gives you dimensions and a surface area that don't match the formula, it's not a real cuboid.
State clearly: "The given surface area is not possible" or "No solution exists". Don't try to force a numerical answer when the math shows it's impossible.
