Решение 3. №75 (с. 193)

Площадь боковой поверхности правильной призмы вычисляется по формуле $S_{бок} = P_{осн} \cdot H$, где $P_{осн}$ — периметр основания, а $H$ — высота призмы.

Основанием призмы является правильный шестиугольник со стороной $a$. Периметр такого шестиугольника равен сумме длин всех его сторон:

$P_{осн} = 6a$

Наибольшая диагональ призмы соединяет две наиболее удаленные друг от друга вершины. Рассмотрим прямоугольный треугольник, образованный наибольшей диагональю призмы ($D$), высотой призмы ($H$) и наибольшей диагональю основания ($d$). В этом треугольнике $H$ и $d$ являются катетами, а $D$ — гипотенузой. Угол наклона наибольшей диагонали призмы к плоскости основания, по условию равный $\alpha$, — это угол между диагональю $D$ и её проекцией на основание, то есть диагональю $d$.

Наибольшая диагональ правильного шестиугольника со стороной $a$ проходит через его центр и равна двум его сторонам:

$d = 2a$

Теперь из указанного прямоугольного треугольника мы можем найти высоту призмы $H$. Катет $H$ противолежит углу $\alpha$, а катет $d$ — прилежит к нему. Воспользуемся определением тангенса:

$\tan(\alpha) = \frac{H}{d}$

Выразим высоту $H$:

$H = d \cdot \tan(\alpha) = 2a \tan(\alpha)$

Подставим найденные значения периметра основания $P_{осн}$ и высоты $H$ в формулу площади боковой поверхности:

$S_{бок} = P_{осн} \cdot H = 6a \cdot (2a \tan(\alpha)) = 12a^2 \tan(\alpha)$

Ответ: $12a^2 \tan(\alpha)$
