A cube has an edge length of 18m. What is its volume, in cubic m?

For this case we have that by definition, the volume of a cube is given by:

Where:

l: It's the side of the cube

According to the statement we have:

Substituting we have:

Thus, the volume of the cube is

The volume of the cube is

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
