Math question: What is the product of 305 multiplied by 2, divided by 5, and then added to 100?

To solve the given expression, we start with multiplying 305 by 2, which equals 610. Next, we divide 610 by 5, resulting in 122. Finally, we add 122 to 100, giving us the final answer of 222. Therefore, the value of the expression is 222.

Math question: Suppose 305 is a three-digit number. If the unit digit is subtracted from the tens digit, and the result is added with the hundreds digit, what number is obtained?

To find the number, we consider 305 as a three-digit number: 3 as the hundreds digit, 0 as the tens digit, and 5 as the unit digit. When the unit digit (5) is subtracted from the tens digit (0), the result is -5. Adding this result (-5) with the hundreds digit (3) gives us a total of -2. Thus, the number obtained is -2.

Math question: What is the minimum number of 305-unit cubes required to form a complete rectangular solid with dimensions 5 units by 7 units by 6 units?

To determine the minimum number of 305-unit cubes required, we calculate the volume of the rectangular solid. The volume is obtained by multiplying the length, width, and height: 5 units × 7 units × 6 units = 210 units³. Since each cube has a volume of 305 units³, dividing the total volume of the rectangular solid by the volume of each cube gives us the minimum number of cubes needed. 210 units³ ÷ 305 units³ ≈ 0.6885. Therefore, we would need approximately 0.6885 or about one-third of a single cube to fill the given rectangular solid completely. Hence, the answer is one-third.
