A cereal box is 8 1/2 inches long, 3 1/2 inches wide, and 12 inches high. what is the volume of the the box?

Length of the cereal box = 8 1/2 inches

= 17/2 inches

Width of the cereal box = 3 1/2 inches

= 7/2 inches

Height of the cereal box = 12 inches

Then

Volume of the cereal box = Length * Width * Height

= (17/2) * (7/2) * 12 cubic inches

= 17 * 7 * 12 cubic inches

= 1428 cubic inches

I think its 357 squared. Just multiply all of it together. I'd check the formula for finding volume if you want a reliable answer
