There are numerous information's already given in the question. Based on these information's the answer can be easily found.
We already know that
Volume = length x width x height
Then
Volume = 10 x 8.2 x 3.5 cm^3
= 287 cm^3
The correct option among all the options that are given in the question is the third option. I hope the answer comes to your help.
Using BODMAS
you do the division first
15+55×66÷(20/100) + 4
15 + 55 × 330 +4
then you do the multiplication next
15 +(55×330)+ 4 = 15 +18150+4
then add all up = 18169
91 is the 25th term because the arithmetic sequence formula is the first term + d(n-1). D is the difference and n is the term u need to find. If i plug in the number you would do 4 x 24 and then -5.
