How much does a block of ice weigh 24ft x 24ft x 4in?

Answer 1

The volume of the block (slab ?) is (24-ft x 24-ft x 1/3-ft) = 192 cubic feet.

We know that ice is slightly lighter than water ... that's why ice floats in water ...

so we have to look up the density of ice before we can say what the slab weighs.

In a quick search on-line, we found one source that gave the density of ice as 0.931,

and another that said it's 0.917. (both relative to water) ... a difference of about 1.5% .

So we know immediately that our answer is going to be only approximate, when we're

done spending as much effort on it as we care to.

First ... the weight of the same volume of water, at 39° F (most dense) =

11,983.9 pounds = 6 tons.

Weight of the same volume of ice (using average of the two density figures

that we found on-line) =

11,071.3 pounds = 5.536 tons (rounded)
