Step-by-step explanation:

The percentage decrease in the surface area of the cube, when each side decreased to 0.5 times the original length is ____________ .

Answer 2

The percentage decrease in the surface area of the cube, when each side decreased to 0.5 times the original length is 75% .

When each side of a cube is decreased to 0.5 times the original length, the new surface area of the cube will be $0.5^2 = 0.25$ times the original surface area.

The total area bounded by all six of the cube's faces is known as the surface area of the six-sided, three-dimensional object known as the cube.

This is because the surface area is directly proportional to the square of the length.

Therefore, the percentage decrease in surface area is:

percentage decrease = (original surface area - new surface area) / original surface area x 100%

percentage decrease $=\frac{ (1 - 0.25)}{1} \times 100\%$

percentage decrease $= 0.75 \times 100\%$

percentage decrease = 75%

Therefore, the percentage decrease in the surface area of the cube is 75%.
