Complete question :
Tim used the expression below, n³ where n represents side length, to determine the volume of a cube. Using this
expression, what is the volume of a cube with side length 3.5 inches? Show your work.
n?
Answer:
42.875 cubic inches
Step-by-step explanation:
Given that :
The formula to obtain the volume of a cube is n³ ; where n = side length of the cube.
The side length of a certain cube is given as = 3.5 inches.
The volume of the cube is calculated thus :
Volume = n³ = 3.5³
Volume = (3.5 * 3.5 * 3.5) inch³
Volume = 42.875 in³
1250. Cubic feet = volume and volume is length * width * height. The volume of this would be 5x5x(1/2), which equals 12.5 cubic feet. 12.5*100=1250
