What is the volume of this figure? a three dimensional figure with sides labeled with values. what is the volume of this figure?

This is just a shape with a peace of it cut out so if we imagine how would this figure be before it was cut. it would give us an 4×12×6 cuboid (we can use that) so first, lets caculate the volume of the bigger cuboid6*12*4=288
THen we need to calculate the volume of the two smaller coupids
4*4*4=64
2*4*12=96

by subtracting the volume of the bigger coupid for our two smaller ones we will have the volume of the tree dimensional figure
65+96=160
288-160=128

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
