Step-by-step explanation:

Volume of a cuboid = (length × breadth × height) cubic units.

= (l × b × h) cubic units.

(Since area = ℓ × b)

Volume of a cuboid = area of one surface × height cubic units

Let us look at the given cuboid.

The length of the cuboid = 5 cm

The breadth of the cuboid = 3 cm

The height of cuboid (thickness) = 2 cm

The number of 1 cm cubes in the given cuboid = 30 cubes = 5 × 3 × 2

We find that volume of the given cuboid with length 5 cm, breadth 3 cm and height 2 cm is 30 cu cm.

it's ok my friend

Step-by-step explanation:

volume of cuboid =l*b*c

{ ({x}^{2}  + 16)}(x + 4)(x + 4) \\ ( {x}^{2}  +16) \:  \:  \:  \:  \: x( x + 4) + 4(x + 4) \\ ( {x}^{2}  + 16)( {x}^{2}  + 4x + 4x + 16) \:  \:  \:  \:  \:  \:  \:  \:  \: using \: identity \:  ({a + b})^{2} = {a}^{2}  + 2ab +  {b}^{2}\\ ( {x}^{2}  + 16)( {x}^{2}  + 16) \\  {x}^{2} ( {x}^{2}  + 16) + 16( {x}^{2}  + 16) \\  {x}^{4 }  + 16 {x}^{2}  + 16 {x}^{2}  + 256 \\  {x}^{4} + 32 {x}^{2} + 256
