This is the concept of algebra, given that the formula for the surface area of the prism is modeled by the expression SA=2s²+4sh , the surface area of the prism when s=3 and h=5 will be found by substituting the values in our expression as follows;
SA=2(3)²+4×3×5
SA=2(9)+60
SA=18+60
SA=78 sq. units
The answer is 78 sq. units

Dana can type 90 words per minute.
Since, 1 minute =
hours
Therefore, number of words she can type = 
= 90×60
= 5400 words per hour
If she types
words in 'x' hours.
