What is the surface area of the solid?
The sum of the area of all of the faces or surface that enclose the solid.
What you need to do is that you plug p=3 into the expression [(5.4p+5)+(8+3.2p)]/2 and you have:
[(5.4*3+5)+(8+3.2*3)]/2
= (21.2+ 17.6)/2
= 38.8/2
= 19.4
The average of the two boys' points is p=3 is 19.4 points~
FIRST ONE: 2
2•10* *= 0 degrees
SECOND: 371
3.71 times 10 2s the two is at the top btw.
THIRD: 875
8.75 times 10 2s the two is also at the top.
LAST: 908
9.08 times 10 2s the two is at the top of 10.
