I know how to do it just then one’s a bit confusing

Answer:

208 ft^3

Step-by-step explanation:

Let the plane through the 4 ft X 4ft square at the top of the figure break the figure into 2 boxes, one has dimensions (8-7) by 3 by 4 = 1ft X 3ft X 4ft, and the other has dimensions 7 by 7 by 4 = 7ft X 7ft X 4ft.

They have volumes of (1)(3)(4) = 12 ft^3, and (7)(7)(4) = 196 ft^3, respectively, so the total volume = 12 + 196 = 208 ft^3, the answer.

Factor the expression.

grigory [225]

Hey!

First, let's write the problem,
$4r^2-64$
Factor out the common term, which is 4,
$=4\left(r^2-16\right)$
Then, let's factor this part: $r^2-16$
We are going to factor it using the difference of squares rule.
$=\left(r+4\right)\left(r-4\right)$
Our final factored answer would be,
$=4\left(r+4\right)\left(r-4\right)$

Thanks!
