What is the volume of the empty part of the box? plz plz plz

One third of the box will be 3 inches long, so is equivalent to a 3-inch cube. It has a volume of

... (3 in)³ = 27 in³

The appropriate choice is ...

... D. 27 cu. in.

Volume is found by multiplying length by width by height. When all are the same (3 in), the product is (3 in)·(3 in)·(3 in) = (3 in)³.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
