Please help, The wording is throwing me off so badly.

sweet [91]

first off, let's recall that a cube is just 6 squares stacked up to each other, like in the picture below. Since we know its volume, we can find how long each side is.

part A)

$\bf \textit{volume of a cube}\\\\V=x^3~~\begin{cases}x=side\\[-0.5em]\hrulefill\\V=64\end{cases}\implies 64=x^3\implies \sqrt[3]{64}=x\implies 4=x$

part B)

they have a painting with an area of 12 ft², will the painting fit flat against a side? Well, it can only fit flat if the sides of the painting are the same length or smaller than the sides of the crate, we know the crate is a 4x4x4, so are the painting's sides 4 or less?

$\bf \textit{area of a square}\\\\A=s^2~~\begin{cases}s=side\\[-0.5em]\hrulefill\\A=12\end{cases}\implies 12=s^2\implies \sqrt{12}=s\implies \stackrel{yes}{3.464\approx s}$

A new crew of painters can paint a small apartment in 12 hours and experience crew can paint a small apartment in six hours how

dalvyx [7]

Answer:

The new crew and the experience crew working together can paint the apartment in 4 hours.

Step-by-step explanation:

Given:

Time taken by new crew of painters to paint an apartment = 12 hours

Time taken by experience crew of painters to paint an apartment = 6 hours

To find the time taken by them to paint the apartment working together.

Solution:

Using unitary method to determine their 1 hour work.

In 12 hours the new crew can paint = 1 apartment

So,in 1 hours the new crew can paint = $\frac{1}{12}$ of the apartment

In 6 hours the experience crew can paint = 1 apartment

So,in 1 hour the experience crew can paint = $\frac{1}{6}$ of the apartment

Now, the new crew and the experience crew are working together.

So, in 1 hour, they can paint :

⇒ $\frac{1}{12}+\frac{1}{6}$

Taking LCD = 12, we will add fraction.

⇒ $\frac{1}{12}+\frac{2}{12}$

⇒ $\frac{3}{12}$

Simplifying fraction we have:

⇒ $\frac{1}{4}$ of an apartment

Again using unitary method to determine the time taken by them working together to paint the whole apartment.

They can paint $\frac{1}{4}$ of an apartment in 1 hour.

To paint 1 apartment they will take = $\frac{1}{\frac{1}{4}}=4$ hours

Thus, the new crew and the experience crew working together can paint the apartment in 4 hours.
