How many feet long and wide is 40 cubic feet?

Answer 1

There's a large number of possibilities for that. It depends on what the height (depth) is.

If it's 1, then there are 4 possibilities using only integers:

1-40

2-20

4-10

5-8

If it's 2 then possibilities are:

1-20

2-10

4-5

If it's 4 then:

1-10

2-5

If it's 5 then:

1-8

2-4

If it's 8 then:

1-5

If it's 10 then:

1-4

2-2

If it's 20 then:

1-2

If it's 40 then:

1-1

So, using only integers there are 16 possibilities.
