He small ball inside the cubed display case has a volume of 8 cubic inches. If the free space inside the display case is 208 cubic inches, then how tall is the display case? 6 inches
8 inches
10 inches
9 inches

6 inches

Step-by-step explanation:

Step 1

Find the volume of the display case

From the above question:

Volume of the small ball = 8 inches

Volume of the free space inside the display case = 208 cubic inches

Volume of the display case = Volume of small ball + Volume of free space

= 8 cubic inches + 208 cubic inches

= 216 cubic Inches

Step 2

How tall is the display case?

The display case is shaped like a square. Hence,

The length of the display case = cube root (Volume of the display case)

= cube root(216 cubic inches)

= 6 inches

Therefore, the length of the cubic display case = 6 inches

If the free space inside the display case is 208 cubic inches, then the display case is 6inches tall.
