find the volume

five hundred eighty-eight cubic inches seven hundred eighty-four cubic inches nine hundred fifteen cubic inches nine hundred eighty cubic inches

OpenStudy (mathmate):

The volume is 2.5 time that of one of the two cubes

OpenStudy (anonymous):

huh?

OpenStudy (mathmate):

You see that the two "cubes" are identical, with sides 7, 7 and 8 units. The triangular prism turns out to be half of a "cube" with the same dimensions. So calculate the volume of one of the two cubes, and multiply by 2.5 should give you the correct answer.
