50 x 8½
300 x 40 = 12000 300 x 8 = 2400 50 x 40 = 2000 50 x 8 = 400 7 x 40 = 280 7 x 8 = 56
Well, isn't that a happy little math problem! If you take 400 and divide it by 8, you'll find that the answer is 50. So, 8 times 50 equals 400. Just like painting a beautiful landscape, sometimes all it takes is a little bit of patience and calculation to find the right answer.
To find a cube number between 400 and 600, we need to calculate the cube root of the two limits. The cube root of 400 is approximately 7.37, and the cube root of 600 is approximately 8.66. Therefore, the cube numbers between 400 and 600 are the cubes of integers between 8 and 7, inclusive. The cube of 8 is 512, which falls within the range specified.
The thickness does not enter into the calculation (400)/(4x32) = 100/32 = 25/8 = 3 and 1/8 No one would sell you 3 and 1/8 boards, hence buy 4 boards
