The total surface area of this cuboid is 112cm squared find the value of x
soldier1979 [14.2K]

Answer:

x=2\sqrt{\frac{14}{3}}\ units  or  x=\frac{2}{3}\sqrt{42}\ units

Step-by-step explanation:

we know that

The surface area of a cube is equal to

SA=6x^{2}

where

x is the length side of a cube

In this problem we have

SA=112\ cm^{2}

substitute in the formula and solve for x

112=6x^{2}

x^{2}=112/6

square root both sides

x=\sqrt{\frac{112}{6}}\ units=2\sqrt{\frac{14}{3}}\ units=\frac{2}{3}\sqrt{42}\ units

Michelle family drove 272.48 miles Michelle calculated that they drove 26.2 miles per gallon of gas how many gallons of gas did
Harman [31]
<span>Michelle family drove 272.48 miles.
=> Michelle calculated that they drove 26.2 miles per gallon of gas.
Question: how many gallons of gas did the car use?
=> Unit rate = 26.2 miles per gallon
Now, they travelled a total of 272.48 miles.
To get the answer let’s divide the total miles they travel to the number of miles for each gallon of gas.
=> 272.48 / 26.2 = 10.2
Thus, they need 10.2 gallon of gas to get to their destination.</span>
