Answer: 42 m² = 452.084 ft²
252 ft squared
6.462"
144 sq ft. length squared to find area
We can't tell without more information. All we know is that when all three dimensions (length in ft, width in ft, height in ft) are multiplied together, the result is 1.2 We're not even so sure of that much, since you haven't told us that the box is a rectangular solid, i.e. all of its inside angles are right angles. It could be a hat-box or pill-box; then, it only has 2 dimensions.
Answer: 42 m² = 452.084 ft²
252 ft squared
This question cannot be answered sensibly. A square foot is a measure of area, with dimensions [L2]. A yard is a measure of distance, with dimensions [L]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
6.462"
21 foot long by 13.5 foot wide for one service box, 21 ft by 27 ft for two.
Diagonal = square root of (24 squared + 26 squared) and that is square root of (576 + 676) and that is square root of (1252) and that is 35.38 feet
27 ft. by 36 ft.
There is no sensible answer to this question. A square foot is a measure of area, with dimensions [L2]. However, the dimensions of the silo are those of a volume [12 feet round by 55 ft tall], with dimensions [L3]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions without additional information.

No box can have a volume of 81 ft because volume cannot be measured in feet.A box with a volume of 81 CUBIC feet could be 1 ft * 1.5 ft * 54 feet.
144 sq ft. length squared to find area
500 ft squared would be 250,000 ft.
