Question

My sister needs help on this! right answer ill choose as an "brainliest" person:)

Answer 1

Find the volume of the rectangular prism as if there wasn't a gap, then find the volume of the gap and subtract it.

$\sf V=lwh$

$\sf V=(12)(6)(8)$

$\sf V=576in^3$

Now the gap:

$\sf V=lwh$

$\sf V=(2)(6)(6)$

$\sf V=72in^3$

Subtract the two volumes to find the volume of the entire figure:

$\sf 576-72=\boxed{\sf 504in^3}$
