Answer:
![\boxed{\textsf{ The total surface area of the cuboid is \textbf{62 cm} $\sf ^2$ .}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctextsf%7B%20The%20total%20surface%20area%20of%20the%20cuboid%20is%20%5Ctextbf%7B62%20cm%7D%20%24%5Csf%20%5E2%24%20%20.%7D%7D)
Step-by-step explanation:
Given that the base area of the cuboid is 7cm² . And it's volume is 21cm³ . We need to find its total surface area . Now here we need to find the height . We can find height as ,
<u>Height</u><u> </u><u>:</u><u>-</u>
Let's find out the Total surface area .
<u>TSA </u><u>of </u><u>cuboid</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Put </u><u>on</u><u> the</u><u> respective</u><u> values</u><u> </u><u>:</u><u>-</u><u> </u>
![\sf\implies TSA_{(cuboid)}= 2( lb + bh + hl )\\\\\sf\implies TSA_{(cuboid)}= 2( 7cm\times 1cm + 1cm\times 3cm + 3cm \times 7 cm ) \\\\\sf\implies TSA_{(cuboid)}=2 ( 7cm ^2+3cm^2+21cm^2 ) \\\\\sf\implies TSA_{(cuboid)}= 2\times 31cm^2 \\\\\sf\implies \boxed{\pink{\frak{ TSA_{(cuboid)}= 62 cm^2}}}](https://tex.z-dn.net/?f=%5Csf%5Cimplies%20TSA_%7B%28cuboid%29%7D%3D%202%28%20lb%20%2B%20bh%20%2B%20hl%20%29%5C%5C%5C%5C%5Csf%5Cimplies%20TSA_%7B%28cuboid%29%7D%3D%202%28%207cm%5Ctimes%201cm%20%2B%201cm%5Ctimes%203cm%20%2B%203cm%20%5Ctimes%207%20cm%20%29%20%5C%5C%5C%5C%5Csf%5Cimplies%20TSA_%7B%28cuboid%29%7D%3D2%20%28%207cm%20%5E2%2B3cm%5E2%2B21cm%5E2%20%29%20%5C%5C%5C%5C%5Csf%5Cimplies%20TSA_%7B%28cuboid%29%7D%3D%20%202%5Ctimes%2031cm%5E2%20%5C%5C%5C%5C%5Csf%5Cimplies%20%5Cboxed%7B%5Cpink%7B%5Cfrak%7B%20TSA_%7B%28cuboid%29%7D%3D%20%2062%20cm%5E2%7D%7D%7D)
Answer:
1. 120
2. 2600
Step-by-step explanation:
6% of 2000 = 120
2000+120(5)
2000+600
=2600
Answer:
![\frac{1}{2}n+1=\frac{2n-22}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dn%2B1%3D%5Cfrac%7B2n-22%7D%7B3%7D)
Step-by-step explanation:
Let's translate the sentence part by part:
Remember "is" means "equal" and "of" means "multiplication"
<u>"One more than one-half a number is ":</u>
![\frac{1}{2}n+1=](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dn%2B1%3D)
<u>"the quotient of 22 less than twice the number and 3":</u>
![\frac{2n-22}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2n-22%7D%7B3%7D)
We can put them together as:
![\frac{1}{2}n+1=\frac{2n-22}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dn%2B1%3D%5Cfrac%7B2n-22%7D%7B3%7D)
This is the equation.
The correct answer would be: 7
To solve this you need to multiply 1/4 by 28.
1/4= .25
.25*28=7
Then you are left with your answer:
7
There are 7 favorable outcomes.
Hope this helps! :3

Step-by-step explanation:
find the circumference of the lid (this is like a side length of a rectangle)
2*pi*2= 12.566in
Then multiply by 3 (the other side length)
12.566*3= 37.7in squared :)
