Для начала необходимо найти длину стороны квадрата, что лежит в основе:Корень из 64 = 8Теперь найдём площадь боковой грани:5*8=40Таких граней 4, следовательно:40*4=160 (суммарная площадь боковых граней)Остаётся только добавить основы (2 квадрата с площадью 64 см^2)Площадь полной поверхности:160+64+64=288 см^2

It took them four years to isolate the radioactive source which she named radium. For this, they gained a Nobel Prize in Physics in 1903. In 1906, her husband died in an accident and Marie got the position they had offered him at the Sorbonne. In 1911, she got a Nobel Prize in Chemistry. When World War I, she designed the first mobile X-Ray machine and travelled with it along the front lines. Marie died in july. 1934 in Paris. She died by radiation poisoning.
