What is the volume of a box in a quadratic equation. (A box has a length of x in., a width of (10–x) in., and a height of 8 in.)

Question

The equation that I need help with is in the parenthesis.

Answer 1

Since all dimensions are given in inches, you do not need to convert any of them.

Formula for Volume:

V = L*W*H [where L=length, W=width, H=height]

V = x*(10-x)*8

V = 8*x*(10-x)

V = 80x - 8x2

V = -8x² + 80x [write terms in descending order of exponents]
