Cube cut

The cube ABCDA'B'C'D ' has an edge of 12cm. Calculate the area of diagonal cut B DD'B '.

Correct result:

S =  203.647 cm2

Solution:

$a=12 \ \text{cm} \ \\ u_{1}=\sqrt{ 2 } \cdot \ a=\sqrt{ 2 } \cdot \ 12 \doteq 12 \ \sqrt{ 2 } \ \text{cm} \doteq 16.9706 \ \text{cm} \ \\ \ \\ S=u_{1} \cdot \ a=16.9706 \cdot \ 12=144 \ \sqrt{ 2 }=203.647 \ \text{cm}^2$
