Dimensions of a pack of 12 cans:

-length :29,2 cm
-Width : 21,9 cm
-height : 10,8 cm
The mass of an empty can is 40g.
The mass of a fully packed shipping crate with cans of fish is 280 kg.
The inner dimensions of a shipping crate are 117 cm by 66 cm by 50 cm.
Packs of cans are placed lengthwise (length to length) in the shipping crates.
Aggie states that an empty shipping crate has a mass of less than 20kg.
Verify,with calculations, if her statement is valid

117/29.2 = 4 packs lengthwise per crate
66/21.9 = 3 packs wide
50/10.8 = 4.62 packs high
so it looks like a crate can hold only 4*3*4 = 48 packs
That is 48*12 = 576 cans
you don't give the mass of a full can of fish, so there's no way to know how much of the 280kg is contents, and how much is just crate.
