The block of goods has dimensions of 2.5 m, 4.2 m, and a height of 180 cm. It is filled to two-thirds of the volume.
How much is hl of water in it?
How many m2 of the tank is soaked with water?

Correct answer:

V =  126 hl
S =  26.58 m2

Step-by-step explanation:

a=2.5 m b=4.2 m c1=180 cm m=180:100  m=1.8 m  c=c1 32=59 32=5 39 2=1518=56=1.2 m V1=a b c=2.5 4.2 1.2=563=12.6 m3  V=V1 hl=V1 10  hl=12.6 10  hl=126 hl=126 hl
o=2 (a+b)=2 (2.5+4.2)=567=13.4 m  S=a b+o c=2.5 4.2+13.4 1.2=501329 m2=26.58 m2
