chest volume is 8100 cubic inches the length is 30 inches and the width is 15 inches how tall will the chest be

The volume of a cuboid is given in terms of length, width, and height by ...

... V = LWH

Filling in the given numbers, we can solve for the height.

... 8100 in³ = (30 in) (15 in) H

Dividing by the coefficient of H, we have ...

... (8100 in³) / (450 in²) = H = 18 in

The chest will be 18 inches tall.
