32 is the answer to the problem
Your y-intercept would be (0,-13)
To calculate the cuboid's volume, use height×width×length which is 11×11×16
For the cylinder's volume, use πr²h. in this case, it is 3.14×4²×9
Add up the two answers you get and that's the solution
In total there will be 688 milliliters of compound used 258 from compound B and 430 milliliters of compound A so 688 in total.
