Acube has a surface area of 1,014 square meters. what is the length of one side.

13 meters. First, you would take 1,014 square meters and divide by 6 surfaces, or faces, for the cube, to get 169 square meters. Then, you would take the square root because each face is a square with equal sides, to get 13 meters. 

wheat acres is 1200.Corn acres is 720.

Step-by-step explanation:

A farm had 480 acres more wheat than corn.W represent wheat.C represents corn.So the equation for this part is:W=C+480.

After the farmers collected 80% of the wheat and 25% of the corn, the area of the wheat was 300 acres less than the area of the corn. So the equation is:W-w-0.8W+300=C-0.25C.which simplfies to:

0.2W+300=0.75C

we have 2 eqations with unknown variables.

W=C+480

0.2W+300=0.75C

we will use the substitution method by plugging in the first equation into the second equation.

0.2(C+480)+300=0.75C.

now solve for C.

0.2C+96+300=0.75C.

396=0.55C

C=720.

solve for W:

W=C+480

W=720+480

W=1200
