A fish tank is in the shape of a cube. Its volume is 125 ft cubed. What is the area of one face of the tank?

Since the volume of a cube is equal to the length cubed, $V= x^{3]$ . Substitute 125 for V giving you $125=x^3$ . Take the cubed root of 125 to give you $x=5$ . To find the area of a side, you have to take the length and square it. Therefore, $A= x^{2}$ . Substitute 5 for x giving you $A=5^2$ . Evaluate the equation to give you $A=25$ .

V=side^3

125=side^3
cube root oth sides
5=side

area=side^2
aera=5^2
aera=25

area=25ft^2

ioda

$\Leftrightarrow q>1\frac{1}{6}$

Step-by-step explanation:

$q-\frac {11}{3}>-2\frac{1}{2}$

$\Leftrightarrow q>-2\frac{1}{2}+\frac {11}{3}$

$\Leftrightarrow q>\frac{7}{6}$

$\Leftrightarrow q>1\frac{1}{6}$
