For this case we are asked the following question:

"What is the volume of the rubick's cube whose edge measures 3 cm"

By definition, the volume of a cube is given by:

V = l ^ 3

Where:

l: Is the side or the edge of the cube

According to the statement we have:

l = 3 \ cm

Substituting:

V = 3 ^ 3\\V = 3 * 3 * 3\\V = 27

Finally, the volume of the cube is 27 \ cm ^ 3

Answer:

4 inches

Step-by-step explanation:

it is given that

1/2" on the blueprint -----> 12 feet actual length

we can rearrange to say :

12 feet actual length ---> 1/2" on paper

or

1 foot actual length = (1/2)" ÷ 12 = 1/24" on paper

hence

96 feet actual length = 1/24 x 96 = 4 inches (answer)
