Calculate how many liters of paint are needed to paint a cube, if the length of the edge of the cube is 2 m

Calculate how many liters of paint are needed to paint a cube, if the length of the edge of the cube is 2 m and approximately 7 m2 can be painted with one liter of paint.

According to the condition of the problem, a cube is given, which must be painted.

It is known that the length of the edge of this cube is 2 meters.

Let’s calculate what the total surface area of the cube is equal to:

S = 6 * a²;

S = 6 * 2² = 6 * 2 * 2 = 6 * 4 = 24 m².

Let’s determine how much paint is needed to paint the entire surface of a given cube, given that one liter of paint is approximately enough to paint 7 m²:

24/7 = 3 3/7 liters ≈ 3.43 liters.

Answer: It takes 3 3/7 liters of paint to paint the entire surface of the cube.
