Length of a rectangular prism is increased by factor of 1.5. The width is doubled and height is tripled. What is the new volume?

dimulka [17.4K]

Nine times the original volume

Step-by-step explanation:

Let the length, width and height of the rectangular prism be 'l' 'w' and 'h'.

The volume of the rectangular prism is given by,

V = W x l x h

The original volume of the rectangular prism is,

V = wlh

Here the length is 1.5 the original length

So, l = 1.5 x l = (1.5l)

And the with is doubled. So,

W = 2W

The height is tripled. So,

h = 3h

Volume of the new rectangular prism is,

V = (1.5l) (2w) (3h)

V = 9 wlh

We know that wlh is the original volume of the rectangular prism.

So the new volume is 9 times the original volume.

Factor completely. . 8x^3-27. Show solution with explanation.

Kitty [74]

Here we are given
8x^3-27
now making both as a cube root
(2x)^3-(3)^3
using formula cube root
 a^3-b^3=(a-b)(a^2+ab+b^2)
where
a=2x
b=3
now putting these values
2x^3-3^3=(2x-3)(2x^2+2x*3+3^2)
simplifying
2x^3-3^3=(2x-3)(4x^2+6x+9)
hence the right answer is
2x^3-3^3=(2x-3)(4x^2+6x+9)
