An ancient unit of length called the cubit was equal to six palms, where a palm was the combined width of the four fingers of a hand. suppose an ark similar to the one that noah is said to have built was 450 cubits long, 50 cubits wide, and 20 cubits high. (take 1 palm to be 0.1 m and give your answers to the correct number of significant figures.) estimate the volume of the ark in cubic meters.
