If a cube has a volume of 9 feet and a shelf has a height of 27 inches, can the cube fit in the shelf?
rusak2 [61]

Answer:

Yes the cube will fit.

Step-by-step explanation:

If we don't take into account of how wide of long the cube is and just focus on the height, the edge of a cube with a volume of 9 feet is roughly 2.08 feet. That totals to less than 27 inches, therefore the cube will fit on the shelf.

Answer:

Step-by-step explanation:

Step 1:

x - > number of Avocado

y -> number of melon

Step 2:

x + y≥ 20

     y ≥ -x + 20

Step 4:

( 1 , 20)

x ≤ 3y               ; y≥ -x + 20

1 ≤ 3*20          ;  20 ≥ -1 + 20

1 ≤ 60              ; 20 ≥ 19
