Question

What is the volume of the following rectangular prism and the top of the shape 9 units squared and the hight is 3 2/3

Answer 1

Answer:

2x^3 + 5x^2 - 18x - 45 m

V = lwh

V = (x + 3)(x - 3)(2x + 5)

V = ((x)(x) + (x)(-3) + (3)(x) + (3)(-3))(2x + 5)

V = (x^2 - 3x + 3x - 9)(2x + 5)

V = (x^2 - 9)(2x + 5)

V = (x^2)(2x) + (x^2)(5) + (-9)(2x) + (-9)(5)

V = 2x^3 + 5x^2 - 18x - 45
