George bought a decorative cover for his tissue boxes. The cover is 5 in. long, 10 in. wide, and 3 in. deep. What is the volume of the tissue box cover?

To find the volume of the tissue box cover, multiply the length, width, and depth together.

Volume = length x width x depth
Volume = 5 in x 10 in x 3 in
Volume = 150 cubic inches

Therefore, the volume of the tissue box cover is 150 cubic inches.
