Amit makes a cuboid having sides 3cm, 2cm & 3cm. How many such cuboids will be required to form a cube.

Tatiana [17]

Start with a volume of a cuboid,

$V=abc=3\cdot2\cdot3=18\mathrm{cm^3}$

The side of the cube we need equals to the LCM of the cubiod's sides,

$\mathrm{LCM}(a,b,c)=\mathrm{LCM}(3,2,3)=6$

Now compute the volume of such cube,

$V=\mathrm{LCM}(a,b,c)^3=6^3=216\mathrm{cm^3}$

Divide the volumes to get how many cubiods are in such cube,

$\dfrac{V_{\mathrm{cube}}}{V_{\mathrm{cubiod}}}=\dfrac{216}{18}=\boxed{12}$

Hope this helps :)

I need helpThe length of a rectangle is (Iunits, and its width is (x + 11) units. Which expression can represent the area of the

balandron [24]

We have a rectangle with length L=x-8 and width W=x+11

Let's remember that the area of a rectangle is given by the following equation

$A_R=L\cdot W$

We replace these values

$A_R=(x+11)(x-8)$

We multiply and solve

$\begin{gathered} A_R=x^2-8x+11x-88 \\ A_R=x^2+3x-88 \end{gathered}$

The answer is option B

Solve the system of equations (1 point)<br> y = 2x(squared) – 3<br> y = 3x - 1

alex41 [277]

$\huge\fcolorbox{blue}{aqua}{Answer:}$

════════════════════

$y = {2x}^{2} - 3$

${2x}^{2} - 3 = y$

${2x}^{2} = y + 3$

$\frac{2x^{2}} {2} = \frac{y + 3}{2}$

${x}^{2} = \frac{y + 3}{2}$

$x = \sqrt \frac{2y + 6}{2}$

───────────────────

$y = 3x - 1$

$3x - 1 = y$

$3x = y + 1$

$\frac{3x}{3} = \frac{y+1}{3}$

$x = \frac{y + 1}{3}$
