The volume of a cubical box is 474.552m3.Find the length of each side of the box

Cerrena [4.2K]

The formula of a volume of a cube:

$V=a^3$

We have $V=474.552\ m^3$

Substitute:

$a^3=474.552\to a=\sqrt[3]{474.552}\\\\a=7.8\ m$

Answer: The length of each side of the box is equal 7.8 m.

How many solutions does the system have?

sertanlavr [38]

If a solution(s) exists y=y so we can say:

x^2-3x=-2x+2 add 2x to both sides

x^2-x=2 subtract 2 from both sides

x^2-x-2=0 factor

(x-2)(x+1)=0

So x=-1 and 2, using y=-2x+2 we find:

y(-1)=4 and y(2)=-2

So the two solutions occur at the points:

(-1,4) and (2,-2)
