I need help pleaseeeee

Answer 1

The answer is D. 245.8 unit^2

Answer 2

`\qquad\qquad\huge\underline{{\sf Answer}}{}`

Surface area of a cube is :

`\qquad \tt \dashrightarrow \:6 {a}^(2)`

where, a represents side length of each edge.

`\qquad \tt \dashrightarrow \:a = 6(6.4) {}^(2)`

`\qquad \tt \dashrightarrow \:a = 6(40.96)`

`\qquad \tt \dashrightarrow \:a = 245.76 \: \: unit {}^(2)`

it can be taken as an approximate of :

`\qquad \tt \dashrightarrow \:a \approx245.8 \: \: unit {}^(2)`
