The surface area of the smaller solid is found to be 214 square meters.

<h3>What is Surface area?</h3>

The surface area is given as the sum of the area of all the faces of a three-dimensional object.

The same shape has equivalent ratio of the surface area to volume. It is given as:

\rm \dfrac{\sqrt{area_1}}{\sqrt{area_2}}=\dfrac{\sqrt[3]{Volume_1} }{\sqrt[3]{Volume_2} }

On considering the power of 6 at both the sides of the equation:

\rm \dfrac{area_1^2}{area_2^2}=\dfrac{volume_1}{volume_2}

Considering area 1 and volume 1 for the larger solid, and area 2 and volume 2 for the smaller solid, substituting the values give:

\rm\dfrac{(856\;m^2)^3}{(area_^2)^3}=\dfrac{(1680\;m^3)^2}{(210\;m^3)^2}

By solving the above equation, the area of the smaller solid is found as 214 square meters. Thus, option B is correct.

Discuss why choosing wrong friends may subject you to unrealistic life expectations.
antoniya [11.8K]
Choosing the wrong friends can lead to a range of problems. To begin with, if your buddies insult others or you, you may become accustomed to being treated badly and direct this energy onto your family. Bad friends may put pressure on you to do things you don't want to do, which could result in negative results. Friends who do not care about your well-being are unlikely to assist you, so you may distance yourself from your family, fearing that they share your sentiments and are uninterested in your well-being. Friends can be disrespectful about your family at times, and this can make you feel obligated to agree with them, which can lead to them being rude to their own family members.

Jessica has 900 feet of fencing and a very large field. She can enclose a rectangular area with dimensions x feet and (450 − x)
lorasvet [3.4K]
P = 2x+2(450-x)=900
A = x(450 - x)
A = x(450 - x)
-x² + 450x = A
-x² +450x = A
A is going to be maximum, when x is a vertex.
-(x² - 450x) = A
-(x² - 2*225x+225²) - 225² =A
-(x-225)² -225² = A
Vertex when x=225

Largest are 225(450-225) = 225² = 50625 ft²

The square has a largest area.
