A jewelry box is designed such that its length is twice its width and its depth is 2 inches less than its width the volume of th
Sedaia [141]

Answer:

Volume = 2x^{3}-4x^{2}

Step-by-step explanation:

Let x be the width of the jewellery box

Given:

Length of the box is twice its width

Length of the box = 2\times width

Length of the box = 2\times x= 2x

depth of the box is equal to 2 inches less than its width.

depth of the box = width-2

depth of the box = x-2

The volume of the box is 64 inches.

Solution:

We know that the formula of the volume is.

Volume = length\times width\times depth

Now we substitute all known value in above.

Volume = 2x\times x\times (x-2)

Volume = 2x^{2}(x-2)

Volume = 2x^{3}-4x^{2}

Therefore, the equation of the volume of the box is.

Volume = 2x^{3}-4x^{2}
