A cube has a volume of 2197 m^3. Its surface is to be painted. Each can of paint covers about 40 m^2. How many cans of paint are
Gelneren [198K]
<em>Volume= a³</em>
<em>a=edge</em>
<em>2197 = a³</em>
<em>=> a=13 m</em>
<em>Surface area=6a²=6*13²=6*169=1014 m²</em>
<em>\frac{1014}{40} = 25,35 ≈ 26</em>
<em>=> <u>26 cans needed</u></em>

Explain why multiplying two irrational numbers could result in either an irrational number or a rational number.
Nimfa-mama [501]
Because if you multiply 2 different irrational numbers (like the following)
\sqrt{3} \times  \sqrt{17}
You will get an irrational answer.

BUT
if you multiply the same square root (which are both irrational, you get a rational number)

\sqrt{3}  \times  \sqrt{3}  = 3
