Consider the long division problem below. what error did sam make when he computed the answer?

The mistake Sam made was to don't write down the dot or the comma after 6. The result of the long division is - 6.3, not -63.

Step-by-step explanation:

1. Let's consider by ourselves the long division problem to understand better what was Sam's mistake.

- 0.2709 ÷ 0.043 = - 6.3

270 ÷ 43 = 6 and 12 as remainder

129 ÷ 43 = 3 and no remainder left

The mistake Sam made was to don't write down the dot or the comma after 6. The result of the long division is - 6.3, not -63.

If we multiply -0.2709 * 10⁴ = -2,709 and if we do the same with 0.043 * 10⁴ = 430. Now let's divide -2,709 ÷ 430 = -6.3, the result should be the same, but like Sam made the mistake it isn't.

1875cm³

step-by-step explanation:

we have a 20 × 20 × 5 container with (what im guessing is a) 5 × 5 × 5 hole in the center. first, we need to calculate the volume of the 20 × 20 × 5 container.

20 × 20 × 5 = 2000cm³

now, we need to calculate the volume of the hole.

5 × 5 × 5 = 125cm³

now to find the area of the container, we take to solid area of the container, and subtract the area of the hole.

2000cm³ - 125cm³ = 1875cm³
