Pool

The prism-shaped pool is 2 m deep with a bottom of the isosceles trapezoid with base dimensions of 10 m and 18 m and arm legs 7 m long and 5.7 m long. During the spring cleaning, the bottom and walls of the pool must be painted. How many m2 of paint should be used?

Correct answer:

S =  163.8 m2

Step-by-step explanation:

h=2 m a=10 m c=18 m b=7 m d=b=7 m h2=5.7 m  S1=(a+c) h2/2=(10+18) 5.7/2=3995=79.8 m2 o=a+b+c+d=10+7+18+7=42 m  S2=h o=2 42=84 m2 S=S1+S2=79.8+84=163.8 m2
