Answer: 8 billion  or 8,000,000,000

====================================================

Reason:

We start with 8 \times 10^9 which is the same as 8.0 \times 10^9

The exponent 9 tells us to move the decimal point 9 spots to the right. If the exponent was negative, then we'd move the decimal point to the left that many spaces.

So we go from 8.0 to 8,000,000,000.0 or simply 8,000,000,000 which is the number 8 billion

Side note: There are 9 zeros in 8,000,000,000

A small refrigerator is a cube with a side length of 12 inches use the formula S= 6s2 to find the surface area of the cube
Luda [366]

Answer:

Surface area of the refrigerator is 864 in².

Step-by-step explanation:

Formula to calculate the surface area of a cube is,

Surface area = 6s²

Here, s = length of a side of the cube

If side length 's' = 12 inches

By substituting this value in the formula,

Surface area = 6(12)²

                     = 6 × 144

                     = 864 inch²

Therefore, surface area of the refrigerator is 864 in².
