Answer:
Width of box is 3 feet
Step-by-step explanation:
Given,
Volume of a box = 30 cubic feet
Length of box= 4 feet
Height of box = 2.5 feet
We need to find width of box.
Since, Volume of box = Length * Height * width
Now plug values for volume, length and height in the above formula and find width.
So,
30 = 4 * 2.5 * Width
30 = 10 * width
Width = 30 /10 = 3 feet
Hence width of box is 3 feet.
