The surface area is 10 square meters, and the height of 40 cm is how heavy the water is, and whether

10 square meters meters = 4 cubic meters.

1 cubic meter of water weighs 1 ton, and the total weight is: 4 tons: 4000kg If 1 person weighs 70kg, 4 tons is equivalent to the weight of 57 people.

Although you don't know the building code and bearing capacity of the balcony, you should also know that the balcony can't bear such a large weight!

10 square meters meters = 4 cubic meters.

1 cubic meter of water weighs 1 ton, and the total weight is: 4 tons: Naijing refers to 4000kg If 1 person weighs 70kg, 4 tons is equivalent to the weight of 57 people.

Although I don't know the building code and bearing capacity regulations of the balcony, I should also know that the Yangchang table manuscript can't bear such a large weight!

40 cm = 40 cm = m.

v=sh=10* cubic meters.

m=pv=10 3*4*10=4*10 3 kg=4 tons According to the national norms, the load of the balcony is 250kg square meters, if it can be loaded, the balcony area must be greater than 4000 250=16 square meters.

When the landlord problem in 10 square meters is 10 square meters, the volume can be calculated as 10 4 * 40 = 400,000 cubic centimeters. Now the density of pure water is 1 gram per cubic centimeter, so the water weighs 400,000 grams, that is, 400 kilograms, that is, 800 catties, a balcony should be absolutely able to withstand it, even if it is not pure water, the density will not be large to there, I hope you can help you.

One cubic meter of pure water is one ton, and you have 4 tons here.

And the general balcony is heavy depends on the design decision, but I think it is okay to tons per square meter.
