Oh, dude, like, 40 cm times 100 cm equals 4000 square centimeters. Yeah, it's like multiplying the sides of a rectangle to find the area. So, it's not a length, it's an area measurement. Math can be sneaky like that.

Well, honey, 40 cm times 100 cm equals 4000 square centimeters. You're not measuring a length here, you're calculating an area. So, next time, make sure you're comparing apples to apples and not mixing up your fruit salad.
To find the area of a rectangle, you multiply its length by its width. In this case, the length is 40 cm and the width is 100 cm. So, to find the area, you multiply 40 cm by 100 cm. The result is 4000 square centimeters.
40 cm x 1 inch/2.54 cm = 15.7 inches (almost 16 inches)
Vol = 10 cm * 5 cm * 40 cm = 2,000 cm3
2.54 cm = 1 in (exactly) 30 cm x 40 cm x 10 cm = (30 ÷ 2.54) in x (40 ÷ 2.54) in x (10 ÷ 2.54) in ≈ 11.811 in x 15.748 in x 3.937 in
