The net on the left is correct.
surface area is the sum of all side areas.

15*5 = 75
5*12 = 60
15*12 = 180
15*13 = 195

75 + 60 + 180 + 195 = 510

15*3=45
5*2=10
12*2=24
13*2=26
10+45+24+26=105

Evaluate

Montano1993 [528]

Step-by-step explanation:

Multiplication of fractions is easiest operation. Simply multiple numerator to numerator and denominator to denominator. For example,

$\frac{x}{y} * \frac{a}{b }= \frac{x*a}{y*b}$

Addition and subtraction requires that we find a common demoninator.

For example,

$\frac{6}{4} + \frac{4}{3}$

The common denominator is 12. So I need to muliply each fraction to get the right denominator. 4*3 = 12.

$\frac{6}{4}*\frac{3}{3} + \frac{4}{3} \frac{4}{4} = \frac{18}{12}+\frac{16}{12}$

Then we add the numerators

$\frac{18+16}{12} = \frac{32}{12}$

Then we should reduce.

$\frac{16}{6} = \frac{8}{3}$

Division is a little trickier because we have to flip-flop the second term and then multiply. For example: $\frac{1}{10} \div \frac{5}{6} \rightarrow \frac{1}{10} * \frac{6}{5} = \frac{6}{50}$
