The block-shaped pool with dimensions of 25 m and 12.5 m and a depth of 2 m is filled with 4/5 of water. Calculate the area of water-wetted areas.

Correct answer:

S =  432.5 m2

Step-by-step explanation:

a=25 m b=12.5 m c=2 m  c2=54 c=54 2=54 2=58=1.6 m  S=a b+2 (a+b) c2=25 12.5+2 (25+12.5) 1.6=2865 m2=432.5 m2
