| February 16, 2021 | education
The surface of a cube consists of six identical faces. The area of one face is equal to the product of its two edges.
S (faces) = a ^ 2.
S (cube surfaces) = 6 * S (faces) = 6a ^ 2.
S (cube surface) = 6 * 172 = 6 * 289 = 1734 m2.
Answer: The surface area of the cube is 1734 m2.
