Question 2

Imagine a shoebox with a length of 12 inches, a width of 8 inches, and a height of 5 inches. How do these measurements determine the volume of the shoebox?

Accepted Answer

The volume of the shoebox is calculated by multiplying its length, width, and height, which is 12 x 8 x 5 = 480 cubic inches.
