Khan academy (8th grade math ) ,

k=37

Step-by-step explanation:

If we plug in 2 for t, which it tells us is the input, then the output of the problem will be 37

k=13t-2

Plug in the value for t.

k=13(2)-2

k=39-2

k=37

all you need to do is multiply length times width times height.

Step-by-step explanation:

5 1/2 x 3= 16.5

16.5 x 2 1/4= 453.75

now just add both answers :)

I really hope this helps! <3 Good luck!
