Question

the length, breadth,height of a cuboid are (x*2+4),(x+2),(x-2) respectively .find its volume

Answer 1

Volume of cuboid is=lbh

[x*2+4] [x+2] [x-2]

[x*2+4] [x*2-4]

X*2-16

X=4

Put the value of x in the given equation

i.e [x*2+4] [x+4] [x-2]

[20] [8] [2]

360

Hence the answer is 360cm*3 or 360m*3

Answer 2

Answer:

Step-by-step explanation:

Volume of cuboid : lbh

(2x+4)(X+2)(x-2)

(2x+4)(x^3-2^2)

(2x+4)(x^2-4)

X^2(2x+4)-4(2x+4)

2x^3+4x^2-8x-16
