Ответ:

102 см².

Пошаговое объяснение:

Если одна грань куба имеет площадь 17 см², то мы можем найти длину каждой стороны куба, извлекая квадратный корень из 17:

√17 ≈ 4,123

Следовательно, длина каждой стороны куба примерно равна 4,123 см.

Чтобы найти площадь поверхности куба, нам нужно найти площади всех шести граней и сложить их вместе. Поскольку все шесть граней куба одинаковы по размеру, мы можем просто умножить площадь одной грани на 6, чтобы получить общую площадь поверхности.

Площадь одной грани равна 17 см², поэтому общая площадь поверхности куба равна:

6 × 17 см² = 102 см²

Следовательно, площадь поверхности куба равна 102 см².
