This is the concept of surface area of solid materials;
The surface area of a triangular base prism is given by:
SA=bh+l(a+b+c)
base=10 cm
a=10 cm
c=10cm
height=8.7 cm
length=15 cm
Thus,
SA=8.7*10+15(10+10+10)
SA=87+15(30)
SA=87+450
SA=537 cm^2
The answer is 537 cm^2

For this Q:
mean=31
st.dev.=0.8
x=32
Calculate z-score:
z=(x-m)/s = (32-31)/0.8=1.25
This z-score value corresponding to the probability of 0.8944
