zhuklara [117]

Answer:

The surface area of door is 33 680 cm².

Step-by-step explanation:

Given that the surface area of a cuboid which is the 3D of rectangle is :

$s.a = 2(l \times w) + 2(l \times h) + 2(w \times h)$

$let \: l = 80 \\ let \: w = 3 \\ let \: h = 200$

$s.a = 2(80 \times 3) + 2(80 \times 200) + 2(3 \times 200)$

$s.a = 2(240) + 2(16000) + 2(600)$

$s.a = 480 + 32000 + 1200$

$s.a = 33680 \: {cm}^{2}$

anyanavicka [17]

Answer: 5%

Step-by-step explanation:

The number of employees that took Winter vacation = 75%

The number of employees that took Both winter and summer vacation = 40%

The number that took Neither = 20

The total number of employees (%) =Winter + Summer - Both + Neither = 100%

75%+ Summer - 40%+ 20%= 100%

Solving for Summer = 45%

Now we are interested in the employees that took summer but not winter = Summer only = Summer - Both(i.e. summer overlap with winter) = 45%-40%= 5%
