Hi, I need help with this task my daughter got in school.
She needs to get how much aquarium full of water weight.
Aquarim size is 25cm x 15cm x 20cm, glass thickness is 1cm.
I have two questions, is my calculation correct and is there an easier way to do it?
Here is my calculation:
Aquarium volume:
25*20*15= 7500cm3
Glass volume:
(25*15*1*2)+(20*15*1*2)=1350cm3 *1000000=0.00135m3
Water volume:
7500cm3-1350cm3=6150cm3*1000000=0.00615m3
Glass Weight:
(Glass density = 2500kg/m3)
2500*0.00135=3.375kg
Water weight:
(Water density = 1000kg/m3)
1000*0.00615=6.15kg
Aquarium weight:
6.15+3.375=9.525kg
