Surface area of the cube
--------------------------------------------------
6(2.5 x 2.5) = 37.5m²
<em>(* Each area is 2.5 x 2.5, and there are 6 sides to the cube)</em>
--------------------------------------------------
Surface area of the rectangle prism
--------------------------------------------------
2(11 x 7) + 2(9 x 7) + 2(9 x 11) = 478m²
<em>(* The opposite side of the rectangle area is the same, therefore x2)
</em>
--------------------------------------------------
Overlapping area
--------------------------------------------------
2.5 x 2.5 = 6.25m²
--------------------------------------------------
Surface area of the composite figure
--------------------------------------------------
37.5 + 478 - 2(6.25) = 503m²
<em>(* The bottom of the cube and the top of the rectangle prism overlapped, so the area is overlapped twice, minus 2 times of that area)</em>
--------------------------------------------------
Answer: 503m²

Answer:
Total
Step-by-step explanation:
A percent bar graph compares the amount in each category to the total amount (sum of all categories) as a percentage.
The question is probably incomplete. What i am assuming is that the person might ask for the previous ratio or the total number of pens and pencil in the drawer.
So if it is the previous ratio it obviously would be 47 - 5 : 17 -3 so 42 : 14 and in case he or she is asking for the total number of pens and pencils in the drawer before so they were 42 + 14 hence 56.
Answer:
Step-by-step explanation:
At most, the area is 140 ---> the area is (3x + 2)10
So, as an inequality, you get (3x + 2) 10 ≤ 140
Simplify
30x + 20 ≤ 140
30x ≤ 120
x ≤ 4
Can 3x + 2 be 15?
Plug in the greatest value of x, and get 3*4 + 2, which is 12 + 2, which is 14
No, at most the length can be 14, which is less than 15.
