If the length of the box is 9 inches, the width is 14 inches, and the height is 20 inches, what is the volume of the box.

2520 inches^3

Step-by-step explanation:

The volume of a rectangular box is given by

V = l*w*h

V = 9*14*20

V =2520 inches^3

2520 cubic inches

Step-by-step explanation:

Length=9inches

Width=14inches

Height=20inches

volume=length x width x height

Volume=9 x 14 x 20

Volume=2520 cubic inches

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
