Question

Round fraction 2/9 to the nearest whole number

Answer 1

Answer: SA=96 sq in.

Explanation:

V=s3

64=s3

find the cubic root of each side

3√

64=s4=s

so the side of the cube is 4 cu in.

The surface area of a cube is

SA=n A where

SA is surface area,

n is the number of faces, and A

is the area of one face.

Te area of one face (A) is s2 so

Answer 2

To round to the nearest whole unit you have to evaluate the tenths place value. If the tenths are less than 5, you keep the ones place and eliminate everything afterwards, otherwise, (if tenths ≥5) you increase the ones place and eliminate all that follows.

2/9≈0.2 since 2<5

2/9≈0 (to the nearest whole number)
