Think of finding each surface area as finding the area of a 2D object
Lets start with the triangle.
area of right triangle = ab/2
6*8=48 48/2= 24
so the triangles surface area is 24, remeber there are 2 identical triangles so multiply 24 by 2 and get 48 again
now lets do one of the rectangles
area of rectangle is ab
so 4*10=40
lets add that to the total
48+40 = 88
Now lets do 8*4= 32
add to total again, 88+32= 120
and now do the last rectangle, 6*4=24
Now get the grand total of it all, 120+24 = 144
Thats how you do it :)

Answer: she will make $232.05 in 4 weeks.
Step-by-step explanation:
Since her profit is increasing by 10% each week, then the rate at which it is increasing is in geometric progression. The common ratio, r would be 110/100 = 1.1
We would apply the formula for determining the sum of n terms of a geometric progression which is expressed as
Sn = a(r^n - 1)/(r - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms(number of weeks)
From the information given,
a = 50
r = 1.1
n = 4 weeks
Therefore,
S4 = 50(1.1^4 - 1)/(1.1 - 1)
S4 = 50(1.1^4 - 1)/0.1
S4 = $232.05
