A pyramid has a volume of 18 in3. If all measures of the pyramid are multiplied by 6, what will the volume be?
guajiro [1.7K]
The formula for solving volume of a pyramid is shown below:
Volume = l*h*w / 3
18 = l*h*w/3
Originally, it is given that the volume of a pyramid is 18 inches³. If we are supposed to multiply all measurements by 6, we can attain new volume and solution is shown below:
New volume = 6³l*w*h /3
New volume = 6³ (18)
New volume = 3,888 in³


The answer is 3,888 inches³.

Write the factors of the following expression x3 (2a‐6)+x2 (2a-6)​
IrinaK [193]

Given:

The expression is

x^3(2x-6)+x^2(2x-6)

To find:

The factors of the given expression.

Solution:

We have,

x^3(2x-6)+x^2(2x-6)

First taking (2x-6) common, the given expression can be written as

=(2x-6)(x^3+x^2)

Taking x^2 common from (x^3+x^2), we get

=x^2(2x-6)(x+1)

Therefore, the factors of the given expression are x^2(2x-6)(x+1).
