The volume of a rectangular prism is calculated as thus:

So, Take for instance



The Volume would be:


Answer:
81
Step-by-step explanation:
just do it step by step adding them together.
Y = kx is the direct variation equation
Substitute the x and y that are given to find k then write your new equation in terms of y with the k.
288 = k(16) divide by 16 to find k
18 = k
Now write the new equation
y = 18x
y = 18(13) or y = 18(-13) I'm not sure by what you have typed if that is supposed to be and equal sign or a negative.
y = 234 OR y = -234
Remember order of operations (PEMDAS):
3•(11-1/2)
3•10.5
31.5
