Answer 1

The slant height is the hypotenuse of a right triangle with legs 471 and 378.

481^2 + 378^2 = L^2
L = 611.76

Answer 2

(1 / 2) * 756 * 611.76 = 231 245.28 --> lateral area of one triangular face

Answer 3

lol @egypt

Answer 4

Total Area = 4 * 231 245.28 + 756*756
Total Area = (4 * 231 245.28) + (756 * 756) = 1 496 517.12 --> Total Area.
