Answer:
1700 cm
Step-by-step explanation
5 x 30 = 150
the total area of the sides is 2 x 150 = 300
the bottom and the top are both 5 by 20 rectangles
so 5 x 20 is 100
and 2 x 100 = 200
the back and the front are both 30 by 20
30 x 20 = 600
6000 x 2 =1200
300 + 200 + 1200 = 1700
300 is the unknown value you're looking for.
°° Why?
Great question! Let's find out! ↓ ↓ ↓
If 90 ÷ 3 = 30, then multiply 30 by 10, which makes 300 to get your answer. It makes perfect sense, doesn't it? :)
So, just fill in the blank!
30% of 300 is 90.
HAHA! We figured it out!

Answer: x < -2
Step-by-step explanation:
Divide -x by 2, and you get -2 making -x turn into a positive x, and since the answer is negative, the inequality flips from right > to left. <
It is a CLOSED circle going left.
