Answer

$1.24\times10^{11}$ cubic feet of water

Work Step by Step

We are given that Lake Mead has a capacity of $124,000,000,000$ cubic feet of water. Step 1: To write this number in scientific notation, we move the decimal point to the left until the original number is 1.24. Step 2: Since the original number was greater than 10, we moved the decimal by 11 positive places. In other words, we will raise 10 to a power of 11. Now, we write the product of the two numbers found in Step 1 and Step 2. $1.24\times10^{11}$ cubic feet of water
