Answer: the height of the box is 12 inches.
Explanation:
The formula for determining the volume of a rectangular box is expressed as
Volume = LWH
Where
L represents the length of the rectangular box
W represents the width of the rectangular box
H represents the height of the rectangular box.
The base of the box is a piece of wood with an area of 90 square inches. This means that
LW = 90 square inches
If the volume of the box needs to have a volume of 1,080 cubic inches, it means that
90 × H = 1080
H = 1080/90
H = 12 inches
