What is the volume of a rectangular prism 11 inches long, 6 inches wide and 3 inches high

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

If t17 = 3 (t5) in an arithmetic progression, find t1 in terms of d.

Multiply and simplify. (x - 4) (x^2 – 5x – 6) i will mark brainliest if your answer is right. show how you got the answer. if your answer is correct but does not show how you got the answer you will not be marked brainliest.
