volume = length x width x height
The formula for the volume of a rectangular prism is:
V = l * w * h
We can replace those variables with 19, 20, and 11 respectively
(l) length = 19
(w) width = 20
(h) height = 11
V = 19 * 20 * 11
V = 380 * 11
V = 4180
The units are in³ because you are multiplying in * in * in = in² * in = in³
V = 4,180 in³
b: |12 – x| ≤ 0.25
let x be the possible lengths in inches, of the ribbons jaime cut.
we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.
we can represent this information in an inequality as:
by the definition of absolute value function we will get,
upon combining our inequalities we will get,
therefore, the inequality describes all the possible lengths (x), in inches, of the ribbons jaime cut.
