What part of the total surface area of a cube with an edge of 0.15 m is the total surface area of a cube with an edge of 0.075 m.
The surface area of a cube is calculated using the formula:
S = 6 * a²
Let’s find the surface areas of both cubes, then compare them.
The surface area of a cube with an edge of 0.15 m is equal to:
S = 6 * 0.15²;
S = 0.135 m².
The surface area of a cube with an edge of 0.075 m is equal to:
S = 6 * 0.075²;
S = 0.03375 m².
Let’s compare the surface areas of the cubes:
0.135 / 0.03375 = 4.
Answer: The total surface area of a cube with an edge of 0.075 meters is 1/4 of the total surface area of a cube with an edge of 0 15 meters.
