Water in aquarium

The aquarium cuboid shape with a length of 25 cm and a width of 30 cm is 9 liters of water. Calculate the areas which are wetted with water.

Correct answer:

S =  20.7 dm2

Step-by-step explanation:

a=25/10=52=2.5 dm b=30/10=3 dm V=9 l S1=a b=2.5 3=152=7.5 dm2 c=V/S1=9/7.5=65=1.2 dm S=S1+2 c (a+b)=7.5+2 1.2 (2.5+3)=20710=20710 dm2=20.7 dm2
