Question

Find the volume of cuboid whose dimensions are (x² – 2); (2x + 4) and (x-3).​

Answer 1

Answer:

As we know that volume of cuboid

Volume = l × b × h

= ({x}^{2} -2) (2x + 4)(x - 3) \\ = (2 {x}^{3} + 4 {x}^{2} - 4x - 8)(x - 3) \\ = 2 {x}^{4} - 6 {x}^{3} + 4 {x}^{3} - 12 {x}^{2} - 4 {x}^{2} + 12x - 8x + 24 \\ = 2 {x}^{4} - 2 {x}^{3} - 16 {x}^{2} + 4x + 24
