the volumes of two similar solids are 210 m3 and 1,680 m3. the surface area of the larger solid is 856 m2. what is the surface a

kolezko [41]

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.

The piece of evidence which President Reagan use to logically conclude that the astronauts were aware of the dangers was the previous accident on the ground

Former President Ronald Reagan gave a powerful speech concerning the Space Shuttle Challenger disaster which claimed the life of all crew members including a teacher.

The shuttle’s launch was said to have been delayed at least two times before the lunch date and due to pressure from the White House, it launch on January 28, 1986.

Due to this previous issues that happened on the ground not space, the shuttle malfunction and burst to flames and if this issues were handled before takeoff, this incident would not have happened.
