The least amount of wrapping paper needed to wrap a cube-shaped gift is 150 square inches. How long is one side of the gift?



Answer :


Isn't the only thing you have to do is since a cube has 6 sides than you would have to do 150 divided by 6. If I am correct.


The length of side of the gift is 5 inches

What is the surface area of cube?

The surface area of the cube will be the sum of the area of the bases and the area of lateral surfaces of the cube. Since all six faces of the cube are made up of squares of the same dimensions then the total surface area of the cube will be the surface area of one face added six times to itself. It is measured as the "number of square units" (square centimeters, square inches, square feet, etc.).

According to the question

The least amount of wrapping paper needed to wrap a cube-shaped gift is 150 square inches.

i.e  Total surface area of cube = 150 square inches

⇒ [tex]6a^{2} = 150[/tex]

⇒ [tex]a^{2} = 25[/tex]

⇒ a =± 5  

(As side cannot be in -ve it should be in +ve always)

therefore , a= 5

Hence, side of the gift is 5 inches
