Question

V=11*9*4
Rewrite the formula using the variable x for the length. Substitute the value of the volume found in step 2 for V and express the width and height of the object in terms of x plus or minus a constant. For example, if the height measurement is 4 inches longer than the length, then the expression for the height will be (x + 4).

Answer 1

V=11*9*4
here 11 is the length
Rewrite the formula using the variable x for the length
so
V=x*9*4
