The answer to this question is 5 days
Equation of a line is given by y = mx + c; where m is the slope.
5x + 2y = 9
2y = 9 - 5x
y = -5/2 x + 9/2
Therefore, slope = -5/2
To find volume, multiply length x width x height.
4 1/2 x 5 x 3 1/4
4.5 x 5 x 3.25 = 73.125
1/4 = 0.25
Divide the total of the large cube to the small cube.
73.125/0.25 = 292.5
292 and 1/2 of the small cube(s) are needed to fill the right rectangular prism.
hope this helps
