Answer 1

6)

$at = 6 {(5)}^{2} \\ at = 6 \times 25 \\ at = 150 {u}^{2}$

$al = 4 {(5)}^{2} \\ al = 4 \times 25 \\ al = 100 {u}^{2}$

8)

Un cubo tiene 2 aristas entonces :

= 120/2

= 60

60/6

=10

$d = \sqrt{ 3{a}^{2} } \\ d = \sqrt{ 3({10)}^{2} } \\ d = \sqrt{3 \times 100} \\ d = \sqrt{300} \\ d = 3 \sqrt{10}$

$at = 6 {(10)}^{2} \\ at = 6 \times 100 \\ at = 600 {u}^{2}$
